KiwiSaver — three sources of money
Every KiwiSaver balance grows from three streams: your contribution (3-10%), your employer's minimum 3% match, and the government's Member Tax Credit (50c per $1 you contribute, up to $521.43/year). Contributing at least $1,042.86 over the year maxes out the government bit — leaving anything on the table is effectively a 50% immediate loss.
PIR — why your tax rate on KiwiSaver is capped at 28%
KiwiSaver funds are Portfolio Investment Entities (PIEs). This means investment income is taxed at your Prescribed Investor Rate — max 28%, not your marginal 33-39%. For higher earners, this is a meaningful tax drag saved over decades. Check yours is set correctly in your KiwiSaver provider's portal; the default of 28% is the right answer for most high-income Kiwis.
Fund type — growth vs conservative
Historical data: growth funds (higher share allocation) have outperformed conservative funds by 2-4% annualised over 10+ year periods, with bigger drawdowns in crashes. If you are 30+ years from retirement, growth or aggressive is the default recommendation. Within ~5 years of withdrawing (for retirement or first home), shift to a balanced or conservative mix.
First home withdrawal + HomeStart grant
After 3 years of KiwiSaver membership, you can withdraw your balance (minus $1000) plus employer and government contributions to buy a first home. Kāinga Ora's First Home Grant (now being wound down) previously added up to $10k per person. Many first homes in Auckland/Wellington are now bought 70-90% LVR using this withdrawal as the deposit.
Frequently Asked Questions
Everything you need to know, in one place.
What rate should I contribute?
Most Kiwis pick 3% (the default). Contributing 4%+ unlocks no extra employer match but compounds significantly over 30-40 years. High earners often use 4-8% to build the tax-advantaged component alongside direct investing.
Can I access KiwiSaver before 65?
Limited early access: first home withdrawal (after 3 years), significant financial hardship, serious illness, or permanent emigration (after 1 year abroad). Otherwise locked until 65.
How much is the government contribution?
Member Tax Credit: 50 cents per $1 you contribute, up to a maximum of $521.43/year. To get the full amount, contribute at least $1,042.86 between 1 July and 30 June.
Which fund type should I pick?
For long horizons (>15 years), growth or aggressive funds historically outperform after fees. Conservative funds suit those near retirement or withdrawing soon. Check returns net of fees and tax (PIR) — fees above 1% eat significantly into compounding.
How does the KiwiSaver first-home withdrawal work?
After 3 years of KiwiSaver membership, you can withdraw your contributions, employer contributions, and investment returns (leaving $1,000 in the account) toward a first home deposit. Combined with the First Home Grant ($3k-$10k depending on property type and region income/price caps), it materially accelerates home buying. You must live in the property for at least 6 months after purchase. Apply via your KiwiSaver provider and Kāinga Ora; allow 10 working days for funds to clear.
Should I compare KiwiSaver providers?
Yes — fees and returns vary significantly. Sorted.org.nz's Smart Investor tool and the FMA KiwiSaver Tracker publish standardised after-fee performance. Top 10-year performers: Milford, Generate, Fisher Funds Growth. Low-fee leaders: Simplicity, Kernel, InvestNow. A 0.5% annual fee difference over 30 years costs ~15% of final balance. Switching is free and takes ~10 business days — no tax event, no employer re-enrolment needed.
