First option, making a first home withdrawal: "The original intention of the KiwiSaver First Home Withdrawal feature was for the money to be used to buy a home (or land on which you intend to build a home) in New Zealand," she says.
"However, the legislation will currently allow you to make a First Home Withdrawal from your KiwiSaver account for an overseas home providing you use a New Zealand practitioner/conveyancer.
"This may change in future.
"In your case, it sounds like you may not be eligible for this as your KiwiSaver money can only be withdrawn to buy land (or a house and land) and you already own your land," says Lockyer.
Anyone who has been in KiwiSaver for at least three years may be able to withdraw their contributions, those of their employer and any investment earnings to put towards a first home deposit.
The government contributions - the $1000 kick-start and any member tax credits earned - need to stay put.
This is set to change in early April when the member tax credit will also be able to be withdrawn to put towards a first home.
If this sounds like it could be an option for you then get in touch with your KiwiSaver provider to get the paperwork under way.
You'll also need to check that your lawyer will be able to make the arrangements for you to settle the overseas purchase - KiwiSaver withdrawals for first home purchases are made into a trust account held by your lawyer on the day of settlement rather than directly to you.
There is another option to release your KiwiSaver funds to put towards building your dream home in the islands.
If you're moving overseas for good then it's possible to unlock your KiwiSaver cash before you retire.
ANZ Wealth's Lockyer explains: "If you are emigrating permanently to the Cook Islands, you may be able to withdraw the funds in your KiwiSaver account under a permanent emigration early withdrawal.
"You must have been living outside of New Zealand continuously for at least a year before you are eligible and you can't withdraw your government annual contributions (member tax credits) or any amount that you transferred to your KiwiSaver scheme from an Australian superannuation scheme," she says.
These rules apply if you're permanently migrating to any country other than Australia.
Like the withdrawal for a first home purchase you will need to get in touch with your KiwiSaver provider.
It will want you to sign a statutory declaration saying you've moved away from New Zealand permanently and will want to see evidence you've lived outside of New Zealand for more than a year.
If, further down the track, you do decide to return to New Zealand you can re-join KiwiSaver but you won't be eligible for another $1000 kick-start.
Moves to Australia are governed by different rules.
A law change in 2013 made it possible to transfer KiwiSaver funds, including the member tax credit and kick-start payments, to an approved superannuation provider in Australia.
Large scale changes in the Australian superannuation industry mean that currently very few Australian superannuation providers are set up to accept KiwiSaver funds.
To my knowledge only Perth-based WA Super has publicly stated it will take KiwiSaver funds, but this is likely to change as more Australian providers gear up to take KiwiSaver funds.
