    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.
