Congratulations! You've officially made it to the retirement age here in New Zealand.
You can now access your KiwiSaver savings and you have a few options, including:
Withdraw your full KiwiSaver balance now
Make regular withdrawals from your KiwiSaver fund
Leave it be and let it grow
Continue contributing to build up that nest egg even more
Keep in mind that even if you're still working and making contributions, the government and your employer don't have to. But have a chat to your boss, they might still be happy to pitch in.
