KiwiSaver is a voluntary work-based savings initiative to help set you up for your retirement. Most members build up their KiwiSaver savings through ‘hassle-free’ contributions from their pay, and an annual government contributions called a Member Tax Credit.
The idea with KiwiSaver is that it builds up over time, earning compounding interest, so when you reach retirement age, it’s there as a retirement nest-egg to supplement your NZ Superannuation.
Contributions are invested into funds of your choice – you can speak to an Adviser to help you select the fund options suitable for your lifestyle and financial situation
You can contribute 3%, 4%, 6%, 8% or 10% of your pay
