Most of the students interviewed were male Indians in their 20s.
The Bay of Plenty Times spoke to two such students on Monday. Neither wanted their names printed but both have worked on kiwifruit orchards.
"It's a hard work to do but it's simple to find a job to earn a little bit [of] money for surviving," one said.
"[Some] kiwifruit contractors are taking advantage of the students. They are giving less than the minimum wage, for example $10 per hour or $9 per hour, it depends on the contractor."
Hundreds of students were being underpaid but none wanted to risk their jobs by complaining, the pair said.
"The students feel angry but they can't do anything else because it's not their home town.
"... If they make an issue with the grower or contractor it will be bad impact on them."
Mat Johnston, BOP chairman of the NZ Kiwifruit Contractors, acknowledged some labour contractors were probably underpaying staff.
"There's no doubt that there are rogues out there, generally fly-by-nighters that are doing that, but that would be the same no matter who the staff are," he said.
New Zealand Kiwifruit Growers chief executive Mike Chapman disagreed with Mr Johnston, saying "the majority of growers stick to the rules".
