Unharvested fruit loss was estimated at 8.6 per cent, while harvested fruit that was not sold amounted to 4.2 per cent.
Council economic development manager Nick Lanham said there could be many reasons for the fruit not making it to market, including labour shortages during the harvest and quality issues when the fruit was being graded in the packhouse.
With food and horticulture innovation and consumer awareness around waste increasing, the time was right to investigate options to support industry to reduce fruit loss, Lanham said.
"There is very little research on food loss in New Zealand and we couldn't find anything published for our local horticulture sector, so doing this research to understand our current situation seemed like a very good place to start."
Reducing fruit loss could support further development of value-added processing options, better growing techniques or new markets, he said.
That would help increase the industry's resilience to weather events or market changes.
"I think it's an opportunity there, but it's not one that growers need to feel like they need to sort of overcome or solve by themselves."
