title: Real Options Analysis of Carbon Forestry Under the New Zealand Emissions Trading Scheme

authors: Tee, James Seng Khien

subjects: climate change

abstract: In 2008, the New Zealand government passed climate change legislation called the New Zealand Emissions Trading Scheme (NZETS), designed to create a carbon price in the economy. Under the NZETS, new forests planted on and after 1st January 1990 (known as post-1989 forests) are eligible to earn carbon credits and sell them domestically and internationally, with a condition that the credits will have to be repaid back upon harvest of the forests. The amount of credits that have to be surrendered is proportionate to the extent that carbon stocks decrease in the forest land. This research explores the effects of the NZETS on new post-1989 forests. The NPV/LEV and the Real Options valuation methods are respectively employed to analyze fixed harvest and flexible harvest forest management decisions. This approach is applied to study the cases of timber-only forestry (i.e. no NZETS) and carbon forestry (i.e. with NZETS). The major advance of this research is the development of a double Random Variable Real Options methodology that incorporates both stochastic timber and stochastic carbon prices into the calculation of the bareland forestry investment opportunity under the NZETS. Through the work of this thesis, it is shown that the NZETS increases the valuation of bareland on which radiata pine is to be planted with a single rotation or a perpetual series of rotations, especially for the case of flexible harvest forest management. The NZETS will very likely lengthen the rotation age of forests and increase forest carbon sequestration, which contributes positively towards climate change mitigation in New Zealand. The Real Options valuation method can generate optimal harvest price thresholds that help forest owners to decide when to harvest. This thesis concludes with a scenario analysis of potential implications of lengthening the forest rotation age on carbon stock management in New Zealand.

title: Health invaders in New Zealand primary schools

authors: Burrows, Lisette

subjects: health policy

abstract: Escalating concern over childhood obesity rates, children’s eating habits and their physical activity regimes has fuelled the development of multiple health policies and resources. Many of these are reaching into primary schools, contouring pedagogical opportunities and influencing how young people may come to understand themselves as healthy (or not). In this paper, we map the health policy/resource context in New Zealand emergent over the past two decades, examining the form and content of health messages circulating and their incursions into primary school environments. We also consider the potential effects for teachers and students of enduring health ‘invasions’ in the primary school space.

title: Māori Women and Gambling: Every Day is a War Day!

authors: Morrison, Laurie Elena

subjects: Maori

abstract: This study was concerned with the health implications of new forms of gambling such as casinos, pokie machines and internet gambling for Māori women and their families in Auckland and the Bay of Plenty region of Aotearoa (New Zealand). It set out to discover what culturally appropriate services were available and the extent to which Māori women gamblers were utilising them. The literature documenting Māori perceptions of gambling shows that Māori women gamblers and their partner/whānau members and gambling service providers have been little studied previously.
These goals translated into the following specific aims: 1) to study how Māori women problem gamblers, their partner or whānau members and key informants perceived gambling, what it meant to them and why they did it; 2) to investigate the consequences of gambling for Māori women, whānau and service providers in dealing with the effects of gambling; 3) to report on how these three groups dealt with the effects of gambling; and 4) to discover what helped to bring about positive changes for the three groups.
 All of the aims were achieved. 
A Māori approach (Kaupapa Māori), combined with a naturalistic approach to data collection, was adopted. Qualitative methods are most appropriate to use when working with some Māori, as there is a growing realisation that research with Māori needs to be interactive. A Māori research procedure modelled on the ritual ceremony of encounter (Pōwhiri) provided an appropriate structure for the development and presentation of the research process. The major focus was on the qualitative data obtained from semi-structured interviews in two locations - Rotorua and Auckland. The interviews were conducted with twenty Māori women gamblers, sixteen whānau members including partners and ten interviews with staff involved in services that provided help for problem gamblers. The three interview schedules were based on a number of broad themes and open-ended questions to obtain meaningful descriptive data. The interviews were audio recorded and used to produce transcripts that were then sent back to the participants for feedback. Qualitative data analysis was conducted on the returned documents. 
The findings from this study revealed major impacts of the women's socio-economic, familial and societal circumstances on gambling behaviour and its effects, which are areas of concern for mental health professionals and researchers. The mythical Māori canoes on which Māori voyaged from their place of origin (Hawaiiki) to Aotearoa, the Waka, provided an appropriate metaphor to present the interrelationship between the pull and push factors toward gambling, and its implications for society. This is illustrated as a spinning waka, Te Waka Hūrihuri. On the other hand, Te Waka Māia (courageous) demonstrates the relationships between the variables that help Māori women gamblers to cope and helpful strategies found to assist them to modify or stop their gambling behaviour. It is recommended that the government limit the proliferation of gaming venues and continue to encourage development of emerging Māori services. Moreover, a coordinated approach is essential, as Māori women gamblers, partners and whānau members need to heal together for positive outcomes for Māori health development in Aotearoa. 
The main implication of this study is that a wide range of further research into Māori and gambling is required. Recommendations on ways in which the current delivery of services in Rotorua and Auckland could be improved are:
 	That the Ministry of Health purchase services that establish support groups for Māori people with problem gambling and their whānau, and
 	That non-Māori provider services and organisations support the development of emerging Māori services.
Heeding the outcome of this research should help improve New Zealand's existing health policy and capacity for Māori women's health development. It should also enrich our understanding of the adaptation patterns of Māori whānau member/s, and thus should have implications, not only for Māori health policies, but also relevance for the wider field of international cross-comparative research on indigenous gambling and mental health issues.  Limitations of this study included a small, localised sample that means the findings can only tentatively be generalised to the wider population of Māori women gamblers. Nonetheless, information gained from the study contributes to understanding of the adaptation patterns of Māori women gamblers, their whānau member/s, and those who are trying to help them.  It is hoped that the study will make it at least a little less true that  every day is a war day  for Māori women and their whānau trying to deal with the problem of gambling.
