"You must not have already used your KiwiSaver funds to buy a first home," says Singleton. Previous home owners apply to their KiwiSaver provider, but HNZ will run the ruler over the application.
It will consider your financial position, including income and the other assets you may have, to ensure you're starting from scratch again. Shares, money on term deposit, classic cars and other assets worth more than $5000 are taken into account. Where you may not be eligible is your joint income. You need to be earning under the $80,000 or $120,000 benchmarks set for the HomeStart grant.
If HNZ did find you eligible, however, it would then be up to your KiwiSaver provider to release your funds, as long as you meet the other requirements - "such as having a valid sale-and-purchase agreement and you have been in KiwiSaver for at least three years," says Singleton.
I recommend getting in touch with your provider when you kick off your house hunt to find out whether your funds are available to buy a home and to walk you through the process.
Buying house and land packages or off-the-plans packages has become easier after rule changes in April. Those who earn $80,000 and under, or less than $120,000 between them, could also be eligible for the KiwiSaver HomeStart Grant run by Housing New Zealand on top of withdrawing KiwiSaver funds.
Once you have been contributing to KiwiSaver for three years you may qualify for an extra $3000 - or $6000 for a couple. Every additional year of contributions to KiwiSaver gives you a further $1000 up to a maximum of $5000 - or $10,000 for a couple. The grant doubles for people buying a newly built home.
As well as the salary cap, there are maximum limits on the house price, which vary between regions.
