NZ household food waste falls again
Kiwis are wasting less of their food than they were two years ago, and this has been enough to push New Zealand’s total household food waste bill lower, the 2025 Rabobank KiwiHarvest Food Waste survey has found.
In its flagship 2015 research report ‘Unlocking productivity growth in the Australian and NZ food & agribusiness sector’, agri banking specialist Rabobank says productivity growth must be reignited to drive farmer profitability.
It says the rising cost of production in recent years has pressured the competitive position of NZ agriculture in the world market and turned a spotlight on Kiwis’ slowing productivity growth.
Reviving this growth is a “particularly pressing issue”, the report warns – given the challenges faced – to reduce NZ agriculture’s environmental footprint while staying internationally competitive.
Individual farmers will have to make productivity gains to drive profitability and sustainability, and other businesses likewise throughout the food and agriculture supply chain.
A particular challenge for NZ, says report co-author Rabobank analyst Georgia Twomey, will be in reigniting sustainable productivity growth in agriculture against the backdrop of strengthening environmental regulation.
“The open market economic reforms in the mid-1980s forced global competiveness to the forefront across the NZ agricultural sector, driving efficiency gains across all parts of the value chain,” she said.
“Additional productivity growth has been derived from changing land use, particularly the switch from extensive sheep and beef farming into dairy production.
“And the significant expansion of irrigated land area – which has doubled every 12 years since 1970 – has also contributed to land use change and increased productivity,” says Twomey.
