    The interface between ethical leadership and food safety culture in Aotearoa New Zealand food businesses : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy, School of Management, Massey University, Palmerston North, New Zealand
    (Massey University, 2025-05-20) Newport-Smith, Wendy
    Measuring, evaluating and improving food safety culture is a priority for Aotearoa New Zealand food businesses. This is driven by the desire to produce food of the highest quality that safeguards consumers, protects the reputation of New Zealand Inc., and meets the requirements of international standards and regulations. This is the first in-depth qualitative investigation into food safety culture and ethical leadership in Aotearoa New Zealand food businesses, including some of this country’s largest food exporters. Using a mixed methods approach this research has provided unique, contemporary understanding and insights, while simultaneously providing a novel contribution to the body of knowledge. Two research workstreams were used; the first a quantitative workstream involving a voluntary survey of manufacturing and distribution employees in New Zealand’s largest food business; a dataset of responses to food safety and ethical leadership questions from 1181 individuals. Using Principal Component Analysis (PCA) applied to Lickert-scale variables, combined with multivariable modelling, this research found a positive relationship between food safety culture and ethical leadership and evidence for differences in responses according to several respondee characteristics. These included associations between PCA coordinates that captured variation in individual responses to food safety and ethical leadership questions, and the supplementary variables: role (e.g. staff or supervisor), site and gender. Ethical leadership has been shown to improve effectiveness, performance and safety at an organisational and individual level. Therefore strategies to improve ethicality across Aotearoa New Zealand food businesses in order to improve food safety culture and ensure safer food outcomes are suggested: consultatively developing organisational values which are well communicated and lived; ensuring ethical considerations when hiring staff; ethical considerations when setting expectations, and in training and mentoring staff and managing performance processes including the use of consequences; and modelling good behaviour, making fair decisions, ensuring open, clear communication and giving employees a voice. While largely positive, the quantitative strand did reveal a level of dissatisfaction with both ethical leadership and food safety culture, suggesting room for improvement. Further research is needed to better understand management’s, supervisors’ and workers’ perspectives on both aspects. The second workstream involved one-on-one semi-structured interviews with 32 founders, owners and senior food safety and quality personnel from 31 Aotearoa New Zealand food companies with thematic data analysis resulting in five key themes: Values; Responsible Stewardship of Natural Resources; Māori Worldview; Ecosystem Pressures and Leadership. The issues identified to be important to Aotearoa New Zealand food businesses include: individual, managerial and organisational values; leadership and management commitment in influencing organisational, food safety and ethical climate and culture; inter-generational value-creation, sustainable practice and acting as kaitiakitanga meaning guardianship or protection. This research has also provided insight into the drivers for and primary challenges related to food safety for Aotearoa New Zealand food businesses. This research has contributed to an up-to-date understanding of the characteristics of ethical leaders in Aotearoa New Zealand, who, according to this study, are humble, honest, respect indigenous Māori values, and are not corrupt. They have a degree of relatedness, care about our natural environment, have a strong sense of identity or place, are collaborative, are fair, and are accountable. Our size, Indigenous Māori worldview, and our geographical isolation contribute to the unique interpretation and application of these leadership characteristics in Aotearoa New Zealand. Several limitations are acknowledged, not the least of which was the context for this research which began at the outset of the global pandemic, with both positive and negative consequences. The use of one, albeit large food business in the quantitative workstream is noted, as is the focus of the participants in the qualitative workstream. Broadening this research to all hierarchical levels in several food businesses would be of benefit, and this is one of a number of research recommendations for the future. The positive correlation between ethical leadership and food safety culture found in this research suggests that maintaining and improving the ethicality of leaders within Aotearoa New Zealand food businesses may positively influence food safety culture and therefore, the production of safer food.

    Place, provenance, protection : alignments, challenges, and opportunities for Māori future foods : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Food Technology at Te Kunenga ki Pūrehuroa, Massey University, Manawatū o Turitea, Palmerston North
    (Massey University, 2025-07-08) Wright, Summer Rangimaarie
    This thesis examines key alignments, challenges, and opportunities for Māori future foods, conceptualised as food production processes and outcomes that positively impact Māori and kinship networks. Beginning with a focus on plant-based future foods, a scoping interview study with Māori enterprise revealed strong alignment with Māori aspirations, including fulfilling kinship responsibilities, bringing together multiple forms of value, advancing collective wellbeing, and protecting and expressing Māori rights and interests - particularly in cultural and intellectual property. Participants identified place branding as a promising avenue to protect and develop cultural landscapes and enable future foods. The second study developed a content analysis protocol to explore the branding of Māori food and beverage packaging, with a focus on the prevalence and potential functions of place elements. Findings show that place branding is widely used by Māori enterprises, affirming its relevance to Māori future foods, while also highlighting a need to understand perceptions of Indigenous place elements. The third study used means-end chain laddering interviews to examine how critical consumers in Aotearoa New Zealand and Singapore perceive Māori place elements. It found a range of positive and negative perceptions across both contexts, which suggest viable approaches to place branding by Māori food enterprise. The thesis presents three key messages: plant-based future foods are relevant to Māori on multiple levels; Māori future foods can be enabled through place branding; and Māori place branding can support enterprise development and the protection of Māori rights and cultural property. These findings have implications for advancing Māori future foods and for growing the research and practice of decolonial Māori and Indigenous place branding. By exploring these interconnections, the thesis contributes to a deeper understanding of how Māori aspirations can shape and benefit from future food systems. It also critiques the ongoing appropriation of Māori culture by government and industry to advance broader agricultural and economic agendas. This research offers a transdisciplinary approach, addressing gaps at the intersection of Māori enterprise, future foods, Indigenous place branding, and consumption studies.

    Risk management by entrepreneurial and non-entrepreneurial micro and small-scale firms in the agriculture food-processing sector in Sri Lanka : a mixed method approach : a thesis presented in partial fulfilment of the requirements for the degree of Doctor in Philosophy in Agribusiness at Massey University, Manawatu, New Zealand
    (Massey University, 2023) Ganegoda Hewage, Ishara Anjalee
    Risk, risk-taking, and risk management have been identified as integral components of entrepreneurship since the inception of the concept of entrepreneurship. However, the relationship between these components still puzzles scholars as different scholars have presented often contrasting theoretical notions and empirical findings regarding how entrepreneurial firms take and manage risk. Despite the importance of risk in entrepreneurship, the attention given to risk management and the adoption of specific risk management strategies is limited in the research literature. The firms operating in the MSME sector play a vital role in economic development in developing countries, particularly in Sri Lanka. The term entrepreneurship is frequently associated and investigated along with the term MSMEs where many researchers have used these two terms synonymously or alternatively. Literature supports the notion that entrepreneurial firms and small businesses are related but they are two different entities with distinctive features. However, the lack of specific criteria to differentiate between the two firm groups is identified as a major hindrance in the sector that negatively affects the development of beneficial policies and scholarly work. With the above questions identified, the overarching research question of this study is; “Do the entrepreneurial micro and small-scale (MSE) firms in the agriculture food processing sector in Sri Lanka manage the risks they face any differently from other MSEs operating in the sector?”. To address this question first it was necessary to assure the existence of such entrepreneurial firms within the sector. For that, the study devised a method to differentiate entrepreneurial firms from their non-entrepreneurial counterparts. Moreover, the study also aimed to investigate the factors that determine the differing risk management behaviour of these MSEs operating in the agriculture food processing sector in Sri Lanka. The research process began with a preliminary study to investigate the context of agriculture food processing MSEs in Sri Lanka. With the support of the findings of the preliminary study and the literature, the five-dimensional Entrepreneurial Orientation approach (i.e. innovativeness, proactiveness, risk-taking, competitive aggressiveness, and autonomy) was identified as the best-fitting method to differentiate between the two firm groups. Upon confirming the existence of entrepreneurial and non-entrepreneurial firms in the sector, the study adopted an exploratory sequential mixed-method approach consisting of two phases; a qualitative phase with selected case firms to explore the nature of their EO followed by a quantitative phase with survey data to investigate the risk management behaviour of a population of these firms. The qualitative phase was conducted with four selected case firms; two entrepreneurial and two non-entrepreneurial to explore the level and nature of EO. The quantitative data were gathered from a sample of 206 MSEs using a structured, researcher-administered questionnaire. The results confirmed that entrepreneurial firms do exist in the agriculture food processing sector in Sri Lanka. Proactiveness, innovativeness, risk-taking, and competitive aggressiveness were identified as the more suitable EO dimensions that can be used to identify and differentiate between entrepreneurial and non-entrepreneurial firms in the Sri Lankan context, with autonomy being identified as not strongly contributing to this differentiation. The study agrees with the existing body of literature on “entrepreneurs are risk takers”, yet goes much beyond of this common notion to prove that they are not only they are risk takers, but also better risk managers compared to their non-entrepreneurial counterparts. The uniqueness of this study is that it has not inly investigated the risk management behaviour of entrepreneurial small firms but also comapred it with a group of non-entreprneurial firms. Quantitative study found significant differences between entrepreneurial and non-entrepreneurial firms in terms of their adoption of risk management strategies. More entrepreneurial firms adopted knowledge-related, strategic, and product price-related market risk management strategies compared to non-entrepreneurial firms. This was also found in the qualitative phase where the entrepreneurial firms were more proactive and showed a notable orientation toward adopting strategic, and knowledge-related, risk management strategies. The two firm groups showed clear differences in their propensities to risk, with two categories of risk propensities identified as entrepreneurial risk (seeking) propensity attributes and non-entrepreneurial risk (averting) propensity attributes. The entrepreneurial risk (seeking) attributes were found to strongly contribute to the differentiation between entrepreneurial and non-entrepreneurial MSEs while the adoption of strategic and knowledge-related risk management strategies was negatively affected by the non-entrepreneurial risk (averting) propensity. Investigating how sources of risk are perceived, both as opportunities and threats, for both entrepreneurial and non-entrepreneurial firms was another important contribution of this study. The results highlighted that the entrepreneurial group perceived more opportunities arising from the sources of risk than the non-entrepreneurial group, with both groups perceiving the threats in a similar manner. Having a proper identification of entrepreneurial and non-entrepreneurial firms is useful for policymakers to devise their policies more strategically. Finally, this study expands the current understanding of entrepreneurial/non-entrepreneurial firms, especially in terms of strategic planning and knowledge-orientation of entrepreneurial firms in managing risks, risk propensity, and perceiving different sources of risks based on the strong foundation of their proactive and opportunity-oriented nature.

    Fractional nonconformance assessment : this dissertation is submitted for the degree of Doctor of Philosophy in Statistics, Massey University, New Zealand
    (Massey University, 2020) Zhou, Xin
    Food quality and safety are important due to the very nature of the product and the potentially severe consequences of a fault in the manufacturing process. Statistical tools are widely used in food quality assurance. However, measurement error, which is inevitable in food manufacturing due to the variation and inaccuracy of the measurement system, affects the performance of statistical quality control activities. The concept fractional nonconformance was recently proposed to assess the probability of nonconformance for error-prone individual measurements. This thesis presents five pieces of work for fractional nonconformance assessment mainly suitable for food quality assurance and other applications. The new statistical methods developed pertain to control charting, acceptance sampling, and conformity testing areas. The application of the proposed methods is illustrated with real data from a leading New Zealand dairy product manufacturer. Interactive web-based Shiny apps providing step-by-step guidance to implement fractional nonconformance analytic tools are developed for practitioners.
