Established in 1880 the Canterbury Society of Arts (CSA) dominated the arts in Canterbury for nearly a century and was the most significant art society in New Zealand. This thesis examines the CSA�s history from 1880 to its change in trading name to the Centre of Contemporary Art (COCA) in 1996 when the Society sought to redefine its role. Chapter One considers its origins, comprising a discussion of the period from 1850 to 1880 in which it was founded as part of an educational complex that reflected Edward Gibbon Wakefield�s ideal for the systematic settlement of Canterbury. A discussion of the Society�s permanent collection from 1881 to 1932 in the following chapter draws attention to how the CSA was guided by its founding ambitions to promote the development of New Zealand art and accompanying responsibilities for art education. Chapter Three considers the premises and art galleries utilised by the Society from 1881 to 1932, revealing that its objectives to advance the arts remained visionary and often demanding. In Chapter Four the period between the Depression and the end of the Second World War is examined and economic and aesthetic challenges, evident in the Society�s limited capacity to purchase works for its collection, alongside the emergence of new art organisations such as the Group are discussed. This is followed by a consideration of the post-war period from the perspective of the CSA�s remarkable secretary from 1943 to 1959, William Sykes Baverstock. His response to an emerging modern movement provides a context to examine significant changes in the arts which initially posed a challenge to the CSA. Consideration of the 1960s to mid-1970s in Chapter Six reveals the vital role played by the CSA in supporting the development of contemporary New Zealand art and includes discussion of significant events and exhibitions such as the Hay�s Art Prize and the expansion of the Society�s programme to include international shows and solo exhibitions of contemporary sculpture, craft, design, and painting. It argues that these activities represented the CSA�s most ambitious and successful period in its history, symbolised by its new modernist-styled gallery which opened at 66 Gloucester Street in 1968. An examination of the late 1970s to mid-1980s in Chapter Seven demonstrates that the CSA continued to maintain its influence as a centre for contemporary arts practice. However, the demands of a greater arts professionalism championed by the Queen Elizabeth II Arts Council and accompanied by a growth in dealer galleries, meant that the CSA also became subjected to criticism and this despite its continuing capacity to expose large audiences to new and challenging arts practices. The close and long-standing relationship between the CSA and the Canterbury College School of Art is considered in Chapter Eight and the way in which this contributed to the Society�s cultural supremacy is acknowledged. The deaccession of 42 important historical works from the CSA�s permanent collection in 1995 discussed in Chapter Nine reveals the extent to which its stature had substantially changed by the 1990s. Its essentially nineteenth-century infrastructure was ultimately inappropriate for addressing new levels of arts professionalism. Chapter Ten concludes that the CSA was a visionary, and sometimes radical, arts organisation that deserves to be more carefully and generously considered. Indeed, its long history reveals a vital arts and educational institution that has made an essential but hitherto hugely underrated contribution to New Zealand�s cultural development.

�Every poet who takes language seriously is working against a culture of clear marketable meanings and commodified production� states New Zealand novelist, essayist and poet Gregory O�Brien. This statement is the motivation for research that is explored in a collaborative ethnographic study of brand culture perceptions in New Zealand. It takes its inspiration from The Poetics of Space (Bachelard, 1978) and provides intimate lyrical insights into the experience of brands and brandscapes. Gregory O�Brien describes the artists that inspire him as: �Those who resolutely stand on their own creative terms, working towards their own objectives, as oblivious as they can be to any market forces.� O�Brien�s observations are relevant to the research project in two essential ways: first to cast light on a shared cultural commodity construct such as a brand from its proposed opposite cultural site of individual imagination and secondly, to accept the poetic in the form of the undiluted voice of vocational poets as valuable media in their own right to achieve insightful interpretations. Critical marketing projects have the duty to generate an alternative �marketing gaze� sufficient to the task of �revelation� (Brownile & Hewer, 2007). With regards to individual artists and poets specifically, critical marketing concepts implicitly pose the main research question as to the scenarios that are conceivably available to consumers: how does �working against marketable meanings� imaginatively work? The project proposes the new construct of co-imagination as the co-active mental and spiritual engagement of consumers with the cultural artefacts of brandscapes that invite individual meaning making. It substantiates this individuality in a poetic evocation of brandscapes by thirteen artists. It analyses the holistic imaginative process on the basis of mental models, strategic scenarios and evocative aesthetics, in order to assess how talented consumers work against marketable meaning. It subsequently offers the relationship of co-imagination with existing co-optive concepts in marketing, literature and consumer behaviour, such as co-creation (Prahalad & Ramaswamy, 2004), co-performance (Deighton, 1992) and co-duction (Booth, 1988). It results in a collaborative artistic inquiry that assembles individual evocations of enchantment and disenchantment with the beauty and ugliness of brandscapes, through newly created poetry. The research introduces the new concepts of aesthetic scarcity and aesthetic community and in its collaborative method of inquiry offers an alternative to a poetic tradition in consumer behaviour of the poet / researcher conflation (Sherry & Schouten, 2002). As a result, the project complements the understanding of the individual meaning-making process in brand culture and is relevant to both practitioners and researchers in consumer behaviour and brand strategy. The design of the project included a four month research journey that covered the North and the South Island of New Zealand with the objective of meeting a variety of poets in their local inspirational environments and brandscapes and catalyse an unusual creative cooperation of highly individual radical artists. In the thick description and analyses of the extensive field research, the project implicitly adds to existing work on brand culture (Schroeder, Salzer Morling, & Askegaard, 2006), brand aesthetics (Saizer-Mörling & Strannegård, 2004) and the relationship between artists and brands (Schroeder, 2005). The research includes design elements based on romantic pragmatism (Rorty, 2007a) and cognitive aesthetics (R. H. Brown, 1977), both post-romantic concepts that explore aesthetic perception as perspectival knowledge and aesthetic distance as a means to transcend the dichotomy of objectivity and subjectivity.

A significant proportion of potential lambs are lost (commonly 15-20%) between ovulation and day 30 of gestation. Moreover, little is known about factors associated with multiple birth capacity of the uterus which would be necessary to convert gains in ovulation rate to the birth of live lambs. This project has investigated the relationship between maternal uterine and hormonal environment as well as the heritability of embryonic survival (ES) in prolific ewes. Litter size (LS) from known ovulation rate (OR) records (n=6393) collected over 16 years were analysed for heritability. ASReml analysis reported ES to be a trait of low repeatability (r� = 0.103) and heritability (h� = 0.04) which is consistent with earlier studies of this trait. However, pedigrees of outlier animals indicated a segregation pattern consistent with a single autosomal gene with a major affect on enhanced ES. From this flock, closely related high ovulation rate ewes with significantly different litter sizes (High ES; OR2.6/LS2.4 versus Low ES; OR2.9/LS1.6) were selected for further study. The anatomy and gene expression of the uterus collected at day 14 of the oestrous cycle (n=5 High and n=5 Low ES ewes) and day 16 of gestation (n=14 high and n=10 Low ES ewes) as well as systemic concentrations of hormones indicative of uterine (activin-A, follistatin) and ovarian (inhibin-α, progesterone) function during the oestrous cycle and early gestation were compared. Progesterone concentrations were found to rise earlier in high ES ewes with a difference in number of ewes with detectable levels of progesterone apparent by day 4 of gestation. The peak concentration and slope of progesterone increase as well as plasma profiles of oestradiol and inhibin-α were not different between groups. A number of pathways worthy of closer investigation were implicated by microarray analysis with Ingenuity Pathway Analysis, Pubmatrix, and candidate gene approaches. In particular, the altered expression of many immune cell factors suggests that high ES ewes have maternal gene expression of the inflammatory pathways favourable to embryo implantation. The plasma concentration of activin, but not follistatin, was found to be significantly higher in low ES ewes, a difference that remained apparent when the concentration of follistatin was corrected for individual samples. Furthermore, the concentration of activin, but not follistatin, was significantly elevated on day 16 of gestation in the uterine fluid of low ES ewes. Further investigation of the pattern of gene expression during the oestrous cycle and early gestation (day10-16 oestrus and days10-20 gestation) revealed that a significant increase in follistatin mRNA in the luminal epithelia and interacting trophoblast cells of the embryo occurs on day 18 and 20 of gestation. It is likely the appropriate balance between activin and follistatin during the time of implantation enhances embryonic survival in this line of ewes. This may be secondary to or concomitant with the observed earlier rise in progesterone concentration. The implication that embryo survival may be positively influenced by a single autosomal gene has important implications for New Zealand's agricultural industry.

Most adult smokers begin smoking during adolescence; nicotine dependence can develop relatively quickly and, once established, most smokers smoke for approximately 40 years. For adolescents dependent upon nicotine, cessation interventions are not well established. It is, therefore, essential that public health interventions focus on preventing initiation and maintenance and decreasing the prevalence of youth smoking. In spite of legislation to protect New Zealand adolescents, a large proportion continues to use tobacco at least weekly. Recent surveys have shown a slight decrease in cigarette smoking prevalence, overall, but, no reduction and marked increases have been reported within some subgroups. The overall aim of this research was to identify school and personal factors associated with secondary school students smoking. The specific research objectives included: a) identifying factors at the personal, family, peer, school and 'tobacco-genic' environment levels which were associated with regular and established cigarette smoking; b) describing the extent of smoke-free policy and health education programmes in secondary schools; and, c) evaluating the relations between cigarette smoking among students and potential protective factors, smoke-free policies and practices and health education programmes. The research was based on data from 3,434 secondary school students from 82 schools. The multi-stage sampling procedures and data analyses ensured that the results were able to be generalised to the New Zealand secondary school student population. Smoking was more prevalent amongst girls for all measures of smoking frequency and significant differences were found for smoking prevalence between ethnic groups and school decile. In terms of family influences, the smoking behaviours of parents were not associated with increased odds of smoking nor were perceived relationships between students and their parents, or exposure to SHS. In contrast, the smoking behaviour of siblings was associated with increased odds of smoking but it is likely that both student and sibling smoking are both influenced by the same processes within the family. Similarly, low levels of self-concept were not associated with increased odds for daily smoking. The smoking behaviour of a best friend was a pervasive risk factor as was a high level of disposable income, frequent episodes of unsupervised activities, and 'pro-smoking' knowledge. Being male, visiting a place of worship, and the intention to stay at school until after Year 13 reduced the odds of daily smoking among students. Multilevel models were used to identify school level effects. After adjusting for student, family and school characteristics significant between-school variance in smoking prevalence remained and this suggests that there are factors, arguably beyond the immediate control of the student or family that may influence a student�s smoking behaviour. The presence of a school effect also supports the WHO concept of 'health promoting schools' in that schools can make a difference to health outcomes. Understanding how the health promoting schools model has been interpreted and implemented in NZ schools, along with critique of the implementation of the amended legislation making all schools smoke-free, would be a pertinent 'next-step' in identifying characteristics of schools which are associated with decreased tobacco use.

This thesis explores the nature of public access rights for outdoor recreation in New Zealand. It aims to improve understanding of these rights by examining the New Zealand public policy framework for public access, the social constructions of access rights and the interaction of these dimensions via analysis of two contemporary New Zealand access issues: the foreshore access debate and the state-sponsored Land Access Review. An institutional arrangements framework forms the study�s conceptual basis and is critiqued for its value in the examination of rights of public access. Multiple qualitative methods were employed to collect data, including interviews with access actors, submission analysis, examination of public policy documents and critical interpretation of the access discourse within the mass media. Key themes from the international access literature are identified and the disparate nature of much of this research is highlighted. Within New Zealand, public access represents an area of research neglect. This thesis provides the first comprehensive study of rights of public access for outdoor recreation in New Zealand. A threshold has been reached in the evolution of access rights in New Zealand. Societal changes are perceived to be reducing the public�s traditional rights to access land for outdoor recreation. Owing to the importance of these rights within conceptions of New Zealand national identity, the Government is codifying access rights in a bid to protect them. Thus a shift in access arrangements is occurring, from reliance upon social customs to increasing use of public policy instruments. Access rights are being renegotiated within a highly contested environment. The debate is being staged within the political arena and via the national news media; access has become a significant national issue. As a result, the level of engagement has shifted from localised access transactions between landholders and recreationists, to a national discussion regarding competing rights to land. Access actors have reacted in different ways to the reforms of access arrangements, driven by the manner in which the proposals affect their property rights, social values and norms. Some reactions have been strident and confrontational. Inadequate public policy arrangements for access have created the 'space' for these multiple social constructions of access to develop. Convergence of a disparate and poorly enforced access public policy framework with varying social representations of access rights is influencing the access outcomes. The 'place' of public access within New Zealand society occurs at the intersection of several strongly-held cultural traditions, including private property rights, Maori customary rights, and a belief that it is a birthright to freely access the outdoors. The tension between these values underpins New Zealand�s unique (and changing) manifestation of the rights of the public to access land for recreation.

Recent New Zealand (NZ) research found rates of physical fighting and weapon carrying among high school students in Dunedin were equal to that of rates for the United States (US). The NZ Government has identified violence as a priority health issue. However, NZ is lacking information on the prevalence of the problem, and the identification of factors which may provide clues for prevention. The current understanding of the social context in which physical aggression takes place, has focused on risk factors that are present in the adolescents� ecological frame. Emerging protective factors are increasingly being recognised as major determinants that can moderate the adverse effects of risk factors. However, little research into protective factors has been conducted in NZ. The aim of this thesis was to investigate physical aggression among adolescents in NZ. This was explored through four in-depth studies: i) a national survey of secondary school principals and counsellors ii) focus groups with students in Otago; iii) an online survey with students in Otago and iv) a survey with teachers in Otago. The national survey of secondary school principals and counsellors points to a degree of concern about physical violence in NZ. One in ten reported fights occurred frequently, and over a quarter of principals and over one third of counsellors reported that at least one student at their school had been caught carrying a weapon. Focus groups with Otago adolescents indicated that fights often began as verbal disagreements escalating to physical fights, that a fight should be defined as serious as opposed to a play fight; and differences were also found between fighting at school and outside of school. Participants suggested that items may be reported as weapons, even though they are not being carried for such purposes. Previous estimates of aggressive behaviours may have been unjustifiably high and possibly hid signifcant differences in the nature of the aggression being reported. A quantitative cross-sectional online survey was undertaken with Otago secondary school students, and confirmed that physical aggression among NZ adolescents is a significant problem. Mutivariate analyses identified the school as an important factor in the social system of adolescents; in particular feeling safe, not feeling alienated and being treated fairly. The results highlighted the need to concentrate on strategies that improve students� positive engagement with school as a means to reduce physical aggression. The final study of Otago secondary school teachers showed that while teachers did not consider physical aggression as a major problem in their schools, they did report frequent occurrences of physical fighting. Respondents also reported some teachers experienced significant physical aggression from students. Physical aggression among NZ adolescents is a significant public health problem that needs addressing. This behaviour impacts directly on the education offered to students, the safety of the environment in which learning takes place, and the stress of the work place for teachers. This thesis has identified school engagement as the most promising protective factors for young people against involvement in physical aggression.

Central southern Fiordland, New Zealand, is underlain extensively by metasediments and associated metavolcanics. These are mapped in three lithostratigraphic units, from west to east Edgecumbe Group, Cameron Group and Cumbrae Supergroup. Lower Cameron Group units lithocorrelate with Central Fiordland Belt lithological associations and with those of Fraser Complex, Westland. Eastern Fiordland Belt metavolcanics and lacustrine metasediments are tectonostratigraphically unrelated to Cameron Group, from which they are separated by the Grebe Fault. They instead have affiliations with the Loch Burn Formation, Largs Volcanics, Drumduan Group and Paterson Group. These units (collectively, "Cumbrae Supergroup") represent remnants of a Triassic-Jurassic calc-alkaline arc. Six deformational episodes are identified in central southern Fiordland. The earliest, D₁, is obliterated by D₂ and M₂ metamorphism. D₃ is restricted to the Southwest Fiordland Block. D₄ occupied a brief interval of M₃ time. D₄ of the Central and Western Fiordland Belts corresponds to earliest deformation in Eastern Fiordland Belt metavolcanics. The Grebe Fault is a left-lateral reverse D₄ fault; now vertical, it previously dipped eastward. The Dusky Fault, a reactivated D₅ left-lateral transfer structure, accommodated the dip-slip component of displacement at low-angle normal faults during mid-Cretaceous extension. Open folds represent D₆. Post-glacial scarps mark the post-D₆ Kilcoy and Vincent Faults. Their merged northward continuation is intersected by the tailrace tunnel of the Manapouri Hydroelectric Power Station. Southwest Fiordland Block pelites were metamorphosed at 665 �C, c. 3 kbar during M₂. Early M₃ is of contact metamorphic aspect. Late M₃ is distinctively polybaric: Central Fiordland Belt kyanite-garnet pelites recrystallised at c. 8.5 kbar after metamorphism in the sillimanite field at c. 3.5 kbar. Western Fiordland Orthogneiss 12 kbar granulite assemblages formed during late M₃. South of the Dusky Fault, late M₃ is almost asymptomatic. The M₃ field gradient is continuous across the Grebe Fault: in the Eastern Fiordland Belt, late M₃ staurolite and garnet supersede chloritoid in lacustrine (meta-)sapropel-silts. The Grebe Fault is an important tectonostratigraphic break; it may separate New Zealand�s Western and Eastern Provinces. Its relationship to any "Median Tectonic Zone" is unclear, as no such zone has been found in southeastern Fiordland. Cumbrae Supergroup rocks within the "Median Tectonic Zone" represent the arc that nourished the Eastern Province�s Barretts Formation, Murihiku Supergroup and Stephens Subgroup. The Cumbrae arc was �obducted� westwards during Early Cretaceous continent-arc collision. This event simultaneously halted Eastern Province volcanogenic sedimentation and tectonically buried Fiordland, imposing late M₃ pressure increments. Drumduan Group lawsonite is coeval. Cretaceous collision induced glaciation. Late Cretaceous climatic deterioration and extensional tectonism caused icecap development. The Otago "Peneplain" is a Late Cretaceous subglacial floor. Accumulation of voluminous perennial Cretaceous ice on Earth has hitherto not been inferred. Facultative psychrophily in New Zealand�s ancient endemics and their preference for dark conditions reflect passage through a hitherto-unsuspected evolutionary bottleneck: prolonged winter darkness and harsh climate of near-polar Late Cretaceous New Zealand exerted extraordinary evolutive pressures on ancestral forms after biotic links with Gondwana were severed. New Zealand�s ancient endemics are the evolutionary derivatives of a Late Cretaceous near-polar fauna.

There was growing concern in New Zealand in the 1990�s that Food Security: access by all people at all times to enough food for an active healthy life, was not being achieved, despite an abundant food supply. A study of a convenience sample of 40 families with children (58 adults and 92 children) whose sole income was a government welfare benefit was undertaken. Two-thirds of these households regularly relied on a limited variety of food; one-half did not have a sufficient amount of food because of lack of money and outstanding debts. Over the previous year two-thirds had sourced food from a food bank and one-third had been gifted food from friends or relatives. Women�s intakes were compromised regularly but not children�s. All of the women experienced worry about feeding their household. One-fifth were overweight and over 40% obese despite low reported daily energy intakes (median (SE) 5.7 (0.5) MJ) compared to national data. Six repeated 24-hour diet recalls collected randomly over a two-week period enabled calculation of usual daily intake and the prevalence of inadequate intake for eight micronutrients which were disturbingly high. The children�s growth patterns compared favourably with US population percentiles. The National Nutrition Survey (NNS97) allowed the adaption of eight questions--developed by Reid using qualitative methods--to eight indicator statements about food security to be addressed by each participant on behalf of them or their household. Prevalence was significantly higher (p<0.05) for females compared to males for the majority of indicator statements among New Zealand European and Others (NZEO) and Maori. NZEO reported the most food security; Pacific people reported the least and Maori fell between the two. There was a significant increasing linear trend of food security with age (p<0.001) after adjusting for gender. Rasch analysis was performed on 1868 households where participants reported some food insecurity. The responses were ranked according to the proportion and ordering of their positive responses to eight indices of food security, achieving reliability (Cronbach�s Alpha) close to the conventionally accepted level of 0.7. The eight indices were ranked on the same scale; the minimum score -1.66 was achieved by the index �use special food grants/banks� (the index least reported and most severe) and the maximum score 1.86 was achieved by the index �variety of foods eaten limited� (the index most reported and least severe). Categories of food security were assigned using scale cut points: �fully/almost fully food secure�; �moderate food security�; �low food security�. Category status was associated with consumption of recommended number of daily serves of fruit, vegetables, fruits and vegetables, consumption of leaner meats, fatty meats and daily serves of bread. By ANOVA and controlling for sex, ethnicity, Index of Deprivation, urban/rural location, age, level of education, income, and household size, category of household food security was associated with the level of daily intake of total fat, saturated, monounsaturated and polyunsaturated fat, cholesterol, glucose, fructose, lactose, vitamin B6, vitamin B12, and vitamin C. Dietary data were from the primary 24-hour diet recall of respondents. Participants in the fully/almost fully food secure category of households had a mean BMI of 28.7 compared to those moderately secure (29.2) and of low food security (29.5) (p=0.015 for difference among categories). In the Children�s Nutrition Survey 2002 (CNS02) data set, the same eight indices were used and food insecurity was experienced significantly more often by children in the largest households, those in the most deprived areas of residence (NZDep01 Quintile) and those of Pacific and Maori ethnicity compared to NZEO children. Rasch analysis was performed on responses for 1561 households with children which reported some food insecurity. Subject reliability was close to 0.7 (the conventionally acceptable level). The distribution of the eight indices on the Rasch scale was similar to that observed among the NNS97 households and almost identical to the sub-set of households with children, from that dataset. Categories of food security status were assigned as in the NN5S97 and they predicted daily nutrient intake levels of children: total sugars, lactose, vitamm A, β-carotene, vitamin B12 and calcium. A more rigorous assigning of categories at the low/moderate scale cut-off, resulted in a further association with level of intake of glucose, fructose and folate. Mean BMI across categories of food security did not differ. Collectively these data provide unequivocal evidence that food insecurity exists in New Zealand, that it can be quantified and associated with nutrition outcomes. It has a negative impact on the nutrient intakes of both adults and children and a negative impact on the body weight status of adults. These data have implications for nutrition and health professionals and policy makers in New Zealand. They also add to the world-wide body of knowledge of the experience of, and the measurement and predictive potential of food security in populations where the food supply appears plentiful.

This thesis examines the personalisation of Pakeha (European) post-mortem practices in New Zealand. While much of the discourse surrounding funerary and disposal processes maintains that contemporary practices demonstrate a �denial� of death and funeral director esurience, funeral directors themselves have argued that the austere Anglophone approach to death has been superseded by personalised practices. This transformation has become particularly evident in the last two decades and emphasises a historic shift to funeral services that encompass the heterogeneity of late-modern individuals. The aim of this thesis, however, is not to recapitulate funeral director rhetoric or reiterate the criticisms levelled at the industry, but to critically examine the implications and manifestations of personalisation, and explore the funeral directors� role in the provision of contemporary funeral services. In addition to archival research, this ethnographic endeavour includes in-depth interviews with funeral directors (and related occupational groups) and an extended period of participant observation. The theoretical issues explored in this thesis are grounded in this ethnographic data. This study reveals that personalisation is integrally linked to constructions of grief, the pastoral role of funeral directors, and Foucault�s concept of bio-power. Funeral director participants asseverated that funeral practices had �evolved� to effect the �healthy� resolution of grief. Personalised funerals represented a re-alignment of �natural� human needs and cultural practices, and funeral director rhetoric amalgamated essentialist interpretations of grief with personalised memories and continuing bonds (Klass and Walter 2001). Funeral directors explicitly linked personalisation to secularisation, emphasising the perceived lack of �guidance� and �care� in contemporary society. Although �impersonal� religious funerals provided funeral specialists with an important point of departure, many funeral directors emphasised the pastoral dimension of contemporary funeral directing. This dimension constitutes a key component of the funeral directors� role and permeated all facets of funeral service - particularly the increasing range of after-care funeral options. Although the funeral director rhetoric emphasises the democratisation of funeral practices and the primacy of individuality, an examination of the discourse reveals that this personalisation also demonstrates the normalising technologies integral to Foucault�s concept of �pastoral power�. I argue that funeral directors play a significant role in articulating the boundaries of �appropriate� funeral behaviour by accentuating the importance of �authenticity�, �dignity� and �healthy grief�. These concepts underline the expertise of funeral directors, define the acceptable parameters of post-mortem practices, and reify the integral involvement of funeral directors in the construction process. The specific subjectivity promoted by funeral directors constitute individuals that are not only �honest� and �real�, but recognise the �need� for a funeral service, emotional expression, and memorialisation. These individuals similarly realise the importance of integrating the deceased into their own biographies, while acknowledging the significance of guidance and control. This subjectivity clearly legitimises the role of the contemporary New Zealand funeral director. This thesis illustrates, therefore, that funeral directors play a salient role in articulating bio-power within New Zealand society, and that this endeavour is integrally linked to the occupations� continuing pursuit of professional identity.

The present study aimed to determine whether stable isotope techniques can be universally applied to detect landfill leachate contamination in aquatic systems. Results of analysis of ��C in dissolved inorganic carbon ([delta]��C-DIC), deuterium and �⁸O in water ([delta]D-H₂O and [delta]�⁸O-H₂O), and �⁵N of dissolved inorganic nitrogen components ([delta]�⁵N-NH₄⁺ and [delta]�⁵N-NO₃⁻) were presented for leachate, surface, and ground water samples collected from seven landfills located throughout New Zealand between 2003 and 2006. The unique conditions within a landfill lead to measurable fractionations in the isotopic ratios of the products of degradation. Results of isotope and ancillary parameter analyses enabled the discernment of different types of leachate, resulting from different microbial processes within the landfill environment. The isotopic characterisation of leachate enabled improved interpretation of geochemical data from potentially impacted surface and ground waters, and provides useful insight to landfill development for landfill operators. A general isotopic fingerprint delineated by [delta]��C-DIC and [delta]D-H₂O values showed leachate to be isotopically distinct from uncontaminated surface and ground water for samples analysed in the present study. However, not all water samples identified as leachate-impacted via site-specific assessments exhibited isotopic values that overlapped with the general leachate fingerprint. This highlights the need to investigate each site individually, within the context of a possibly global leachate isotope signature. Site-specific investigations revealed the effectiveness of applying [delta]�⁸O-H₂O and [delta]�⁵N-NH₄⁺ or [delta]�⁵N-NO₃⁻, in addition to [delta]��C-DIC and [delta]D-H₂O analyses, to the detection of leachate impact on aquatic systems. Furthermore, ancillary parameters such as alkalinity and ammonium concentration enabled the construction of simple isotope mixing models for an estimate of the quantity of leachate contribution. Results of isotopic investigations of stream biota suggested potential for the development of bio-indicators to monitor leachate influence on aquatic ecosystems in landfill-associated streams. The present study demonstrated the probative power of stable isotope techniques applied to investigations of leachate impact on landfill-associated aquatic systems.
