Since a labour shortage was declared in Hawke's Bay more than 300 jobseekers had been connected with the horticulture industry.
"The weather conditions this summer, with more heat and rain, has seen a bumper crop produce bigger volumes of larger apples. Although we're providing all the people we can to help with seasonal work opportunities through Work and Income, more are still needed."
Mrs Aranui said the remaining 50 per cent of crops would be ready for harvesting soon.
"Industry have informed us that heavy crops take longer to mature and the time needed to pick them needs to be extended to account for that."
About 14 million cartons of apples will be packed this year in the Hawke's Bay, which is an additional two million cartons compared to last year.
Hawke's Bay Fruitpickers Association president Lesley Wilson said grower were "very grateful" for the extension but the region was still short of a "significant number" of backpackers.
"Growers are still struggling but every little bit helps.
"We are still managing but the next couple of weeks will be critical."
When the labour shortage was first declared, orchards in the region were in need of about 400 people more than usual.
By declaring a labour market shortage all growers within the Hawke's Bay area will be able to employ fruit pickers who are not necessarily New Zealand Jobseekers, and are on visitor permits.
However, Bostocks labour resources manager Vikki Garrett said while inquiries from backpackers had been flowing in, those inquiries were not coming to fruition.
"Last week we had maybe seven people sign up and they were predominantly locals. So, as far as backpackers coming out of the woodwork - that hasn't happened."
Ms Garrett pointed out that apple pickers needed to pick three bins a day to "break even" with the national minimum wage - but a good picker could pick between six and eight bins a day.
"Then they will be earning around about the $800 to $1000 a week mark."
