Why Amp and Bnz differ
AMP and BNZ differ most sharply on fees and fund range. AMP's scheme spans 30 funds with an average fee of 0.998%, while BNZ offers 8 funds at an average fee of 0.419%, less than half AMP's level. AMP also reports a higher average 5-year return across its range at 6.47% versus BNZ's 3.98%, a gap of 2.49 percentage points, though this spread should be read alongside the fee difference rather than in isolation, since neither figure is net of the other.
Scale differs too: AMP holds larger total assets under management at roughly $9.70 billion against BNZ's $7.16 billion, yet BNZ serves more members, 254,670 compared with AMP's 219,095, pointing to a lower average balance per member on the BNZ side.
On cost extremes, AMP's lowest-fee option is the AMP Cash Fund at 0.65%, while BNZ's cheapest is the BNZ KiwiSaver Cash Fund at 0.30%. Both providers list a top fund by name, AMP's Milford Active Growth Fund and BNZ's Default Fund, but neither snapshot includes a five-year return figure for that specific fund, so fund-level return comparison isn't possible here. Both operate a single scheme structure rather than multiple trust vehicles.

Highest 5-year return funds
Reading the data: which provider suits which investor
Lower headline fees: Bnz (0.42% average) versus Amp (1.00%). Fee-sensitive investors and long-horizon savers (20+ years to retirement) typically weight fees heavily because they compound.
Higher historical 5-year return: Amp (6.47%) versus Bnz (3.98%). Higher past return is not a forecast — it usually reflects asset-mix differences (more growth assets) and the specific 5-year window. A higher-growth portfolio also carries larger drawdowns.
Wider fund range: Amp (30 funds) gives more granular control over asset allocation across categories. The provider with fewer options (8 funds) is typically more index- or default-fund focused.
This is data analysis, not advice. Whether either provider suits you depends on your investment horizon, risk tolerance, and personal circumstances. Consult a licensed financial adviser for guidance specific to your situation.
Switching from Amp to Bnz (or back)
- Decide the destination fund. Pick the specific Bnz fund that matches your target risk profile (Conservative / Balanced / Growth / Aggressive).
- Apply with the new provider only. You do not need to contact your current provider. The new provider initiates the IRD/transfer process on your behalf.
- Wait 10–15 business days. Funds transfer at unit price on the day of transfer. There are no exit fees, tax penalties, or contribution interruptions.
- Update your PIR if needed. A change of provider is a good prompt to confirm your Prescribed Investor Rate (PIR) is correct.
You can only be in one KiwiSaver scheme at a time. Switching between funds within the same provider is a separate, usually instant process — see our switching-funds guide.
