Avocado New Zealand's Bevan Jelley said it was common for prices to drop at this time of year when the bulk of fruit began to be harvested. However, there was nearly twice as much on offer compared to last year.
"Volume for this season is quite a bit larger than what there was last season," he said.
"For the New Zealand market, from May, we have harvested 589,000 trays. At this time last year we had harvested 356,000 trays."
Mr Jelley said it was not just New Zealand's supply of the fruit that had swelled. Avocados for export and processing had risen to a forecast 7 million tray count for the season, that peters off in the late summer months, compared to 4.9 million last year.
Pukekohe Vegetable Growers Association president Bharat Jivan said there was an abundance of lettuce in the market, which meant prices were likely to be lower for consumers. "Guys are not even harvesting them because they are so cheap," he said.
R C Hari and Sons grower Kiran Hari said there was an oversupply of lettuce heads because consumers were buying more pre-packaged bags of greens.
"There is an abundance of good quality lettuce out there," he said.
"There is also more people buying bagged lettuce, so we are in a boat where we won't harvest if we won't get a return on it."
A Countdown spokeswoman said its avocado price was popular with customers and agreed that the popularity of bagged loose lettuce was on the rise.
"The key drivers of this are convenience and shelf life," the spokeswoman said.
