In order to understand New Zealand’s food waste issue Love Food Hate Waste partnered with the University of Otago, WasteMINZ and councils from around New Zealand to conduct research in 2014/2015.
Using the tools below we sought to find out how much food New Zealanders waste, what kind of food and why.
These audits separated out food waste from kerbside collections. The food waste was then analysed to understand how much food waste is:
- Avoidable, i.e. could have been eaten e.g. a slice of bread
- Potentially avoidable e.g. apple and potato peels
- Unavoidable e.g. banana skins
These audits provided information on the most commonly wasted foods and the costs of food waste to households. Bin audits were undertaken in Auckland, Waipa, New Plymouth, Wellington, Selwyn District and the Canterbury region with 1,402 bins audited.
Between February and July 2018 we conducted 600 bin audits of domestic kerbside refuse at six locations around New Zealand. This was a smaller scale version of the 2014-2015 bin audit research.
The aim of this survey was to obtain greater insight into the attitudes and perceptions of why people waste food. The survey was completed in September 2014 with 1,354 participants.
In 2018 we repeated the online survey to measure if there had been any changes in people attitudes and behaviours towards food waste.
These provide insight into why food is being thrown out. 100 households were asked to keep a diary for one week and record:
- What food they are throwing out
- The quantity of wasted food
- Why they are throwing it out
- Where it is being put e.g. composted, insinkerator or in the rubbish.
Kitchen diaries were completed in Nelson/Tasman, Wellington and New Plymouth.
Auckland Council conducted 27 in-depth interviews with individuals who were responsible for purchasing and/or preparing food within their households.
