Figures released to Newstalk ZB show the amount of people taking money from their retirement fund for financial hardship reasons has increased dramatically from 200 in 2008 to more than 8000 in the last financial year.
Those aged between 35 and 44 were the most likely to withdraw, with 2,300 doing so last year.
The amount that can be withdrawn is limited to that which will alleviate the particular circumstances of hardship.
One Christchurch man said he had exhausted all other options when he decided to withdraw money from his KiwiSaver because of financial hardship.
Graedon Parker had to prove how bad his situation was before he could withdraw money to try and raise cash for his new business.
