Mr Hendry said demand was strong because families thought their usual fare - summer harvested fruit - too expensive at about $8.99 a kg but they still wanted healthy eating and they saw value in a kilogram of bananas for $2.99.
MG is a major supplier to supermarket giant Foodstuffs, whose group marketing general manager, Steve Bayliss, said supply had been tighter than normal for its New World, Pak'nSave and Four Square stores. However, it managed to procure enough stock from across the brands of Dole, Fyffes and Bonita to meet customer demand over summer and did not expect to run out in the next two to three weeks.
Green-yellow bananas only were on sale at the New World Metro store in Queen St, Auckland, yesterday and three cost $1.76 at the $2.99 a kg ticket price.
At the rival Countdown supermarket chain, a company spokesperson said it did not have a shortage of bananas but had received "a number of bananas which are not up to our high standards".
Veteran fruit and vegetable retailer in the Remuera shopping centre Jack Lum said some of the four wholesale markets for bananas had offered better quality than others during the past three weeks.
"Customers buy with their eyes, so a bit of marking they don't like, or even if it's on the green side and discoloured."
A problem with quality was denied by Dole supplier MG Marketing, Turners & Growers (Bonita), and Freshmax (Fyffes).
