<p>This thesis investigates preferences for housing, neighbourhoods, and transport in Auckland, New Zealand, supplemented by a comparison with similar research in Wellington and Hamilton. The topic is significant for New Zealand as there is an increasingly urban population, and the interconnected areas of urban form and transport can help the country reduce carbon emissions and provide a healthier, more enjoyable lifestyle for its people. The influence of residents’ preferences and their relationship with urban form on achieving compact city development is investigated.  Historical and current planning rules and policies provide context for an analysis of how urban planning, preferences, and location and travel choices interact. Auckland’s housing and transport policies show a pattern of path dependency: decisions favouring greenfield development, sprawling low-density suburbs, and car-centred transport have driven subsequent investments and influenced the ease of using alternative transport modes. Such rules have also reduced the availability of housing in accessible, medium- to high-density neighbourhoods and may have contributed to the rising costs of this type of housing.  A stated choice survey of 3,285 Auckland households was conducted to investigate the extent to which there is an unmet demand for compact development and alternatives to car travel.  Using the survey results, a multinomial latent class model was developed to examine the preferences of households and the trade-offs they may be willing to make when choosing where to live. This type of model allows for identification of preference groups as a means of understanding the heterogeneity of preferences across the population. There was an unmet demand for accessible, medium-density housing, with some households willing to trade off dwelling size and neighbourhood type for higher accessibility or lower prices. The study also found that more people currently drive than would prefer to, with long journey times, safety concerns, unreliable services, and a lack of infrastructure acting as barriers to active and public transport. Households preferring low density are more likely to occupy their preferred dwelling type and be able to use their preferred transport mode. In contrast, those preferring high accessibility or driven by price are more likely to experience a mismatch between their preferred and current dwelling type, and are less likely to be able to use their preferred transport mode.</p>

Compact Development

<p>This thesis investigates the scope for compact development to accommodate population growth in Wellington, New Zealand. The topic is particularly significant for New Zealand as the great majority of the population lives in urban areas, historical development has been dominated by low density urban form, and transport and urban form are two of the main domains in which the country can reduce its carbon emissions. The influence of urban planning and residents’ preferences on achieving sustainable outcomes is investigated.  Historical and current planning rules and transport policies in the City are analysed to determine their influence on the provision of compact development. Wellington’s transport policy shows a pattern of path dependency: historical decisions to favour car oriented investment have driven subsequent transport investments and influenced the ease of using different transport modes. Planning policies show a similar pattern of path dependency: planning rules enacted in the 1960s endure in present planning despite being packaged with different justifications and regulatory regime. Current planning rules severely restrict infill development in most existing neighbourhoods, which reduces the availability of housing in accessible medium density neighbourhoods and likely increases the cost of this type of housing.  A stated choice survey was conducted of 454 residents of Wellington City to investigate the extent to which there is an unmet demand for compact development and alternatives to car travel. The survey held presentation mode constant across two completion modes (internet and door to door with tablet completion), allowing the impacts of recruitment and completion mode to be examined. Survey recruitment mode appeared to influence both response rates and the representativeness of the survey, while completion mode appeared to have little or no impact on survey responses.  Using the stated choice survey results, a latent class model was developed to examine the preferences of residents and the trade-offs they are willing to make when choosing where to live. This type of model allows for the identification of preference groups as a means of understanding the diversity of preferences across the population. The study found that there is an unmet demand for medium density, accessible housing, but that affordability is a barrier for households to choose this type of housing. There was also an unmet demand for walking and cycling, with more residents currently driving than would prefer to use this mode, and more residents preferring to walk and cycle to work than currently use these modes. The ability to use a desired travel mode appears to be related to the neighbourhood in which a person lives, with residents of medium and high density neighbourhoods being more likely to use their preferred travel mode.  This study also modelled future development trajectories for Wellington based on demand for housing, neighbourhood and transport attributes. This preference based growth model was contrasted with the City’s plan for development over the next 30 years. Comparing the two scenarios, the planning based trajectory performed better than the demand based scenario in terms of both carbon emissions and achieving compact development.</p>

During summertime in New Zealand, white clover experiences high levels of ultraviolet-B (UV-B) radiation. This frequently coincides with periods of summer drought. We investigated responses to UV-B and to the combination of UV-B and drought in various white clover populations, including New Zealand cultivars and ecotypes as well as overseas germplasm. The results were obtained under controlled environmental conditions in three independent trials. Overall, white clover growth was reduced by UV-B. The population comparisons indicated that low growth rate and adaptation to other forms of stress may be related to UV-B tolerance under well-watered conditions, but not during extended periods of drought. Flavonoid pigments that are involved in stress protection were strongly increased under UV-B and were further enhanced in the combination of UV-B and drought. The responses among these flavonoids were highly specific, with more pronounced UV-B-induced increases in quercetin glycosides, compared to their closely related kaempferol counterparts. UV-B toler ance of the less productive white clover populations was linked to the accumulation of quercetin compounds. In conclusion, these studies suggest (i) that slow-growing white clover ecotypes adapted to other stresses have higher capacity for biochemical acclimation to UV-B under well-watered conditions and (ii) that these biochemical attributes may also contribute to decreased UV-B sensitivity across white clover populations under drought. The findings alert plant breeders to potential benefits of selecting productive germplasm for high levels of specific flavonoids to balance trade-offs between plant productivity and stress tolerance.

Major Barrier

Many retailers have expanded and diversified their private label food product assortment by offering premium-quality private label food products such as organic products. With price being identified as the major barrier for organic food purchases, private label organic food products could be a suitable and more affordable alternative for many consumers. While numerous studies have examined consumer preferences for organic food, very few organic food studies have incorporated the concept of private labels. This study addresses this research gap by studying consumer preferences and willingness to pay for national brand and private label organic food using a latent class model. Specifically, this study analyzes consumer preferences for organic eggs and orange juice and the effect of national branding versus private label. Findings show heterogeneity in consumer preferences for production method and brand, with three consumer segments being identified based on their preferences for both juice and eggs. For eggs, about half of the consumers prefer private label and organic production, whereas one-quarter clearly prefers organic, and another quarter is indifferent about the brand and the organic production. For orange juice, the majority (75%) prefer the national brand. In addition, one-quarter of the consumers prefers organic juice, and about one-third values both organic and the national brand.
