How to make voluntary contributions

You can make voluntary contributions (or lump sum payments) at any time, either directly to your KiwiSaver provider or though Inland Revenue.

Once you've made a lump sum payment it's "locked in" until you're eligible to withdraw your savings. You can make payments directly to your KiwiSaver provider. 

Payments through Inland Revenue can be made in three ways.

Internet banking

Choose the "Pay tax" option on your internet banking service. You need to include:

• your IRD number
• the tax type "KSS", and
• period "0" (zero).

At Westpac

Pay over the counter at any Westpac branch.

By cheque

Send a cheque to Inland Revenue with a completed payment slip to: 

Inland Revenue, PO Box 1454, Hamilton 3240, New Zealand
