KiwiSaver for First Home Buyers: 5 Mistakes to Avoid
For many New Zealanders, KiwiSaver plays a key role in getting onto the property ladder. But when you’re planning a first home purchase, the way your KiwiSaver is set up matters more than most people realise.
Here are five common mistakes first home buyers make – and how to avoid them.
1. Being in the wrong fund
If you’re planning to buy within the next one to three years, being in a growth or aggressive fund could expose your deposit to unnecessary market risk.
Growth funds are designed for long-term investing. Short-term market drops could reduce your balance at the wrong time.
If your timeframe is short, it may be worth reviewing your risk level.
2. Waiting too long to check your balance
Many people only look at their KiwiSaver when they start house hunting.
Instead, check early:
- How much you’ve saved
- How much you could withdraw
- Whether your contributions are enough
Knowing your position early helps you plan realistically.
3. Not understanding what you can withdraw
For a first home purchase, most people can withdraw:
- Your contributions
- Employer contributions
- Investment returns
The only amount that stays in your account is the $1,000 government kick-start (if applicable) and recent government contributions.
Understanding what’s actually available can change your deposit strategy.
4. Missing additional support
Depending on your income and the property price, you may be eligible for:
- Kāinga Ora support
- Other assistance options
These can make a meaningful difference, but the rules and eligibility criteria can be confusing.
5. Focusing only on KiwiSaver
KiwiSaver is just one piece of the puzzle.
You’ll also need to consider:
- Ongoing affordability at current interest rates
- Emergency savings after purchase
- Whether to keep additional savings separate from KiwiSaver
A balanced approach helps you avoid becoming “asset rich but cash poor”.
When should you review your KiwiSaver?
It’s worth getting advice if you:
- Plan to buy within the next three years
- Aren’t sure what fund you’re in
- Don’t know how much you can withdraw
- Want to make sure you’re not taking unnecessary risk
Final thoughts
Your KiwiSaver could be one of the biggest contributors to your first home deposit. A small adjustment now – especially around risk level and timing – can help protect what you’ve worked hard to save.
