Why Amp and Westpac differ
AMP and Westpac differ most clearly on fees and fund range. AMP discloses an average fee of 0.998% across 30 funds within its KiwiSaver scheme, while Westpac's average sits at 0.45% across a narrower set of 8 funds. That spread carries through to the cheapest options in each range: AMP's lowest-fee fund, AMP Cash Fund, charges 0.65%, compared with Westpac's Cash Fund at 0.25%.
Scale runs the other way. Westpac reports higher total assets under management, at roughly $12.62 billion versus AMP's $9.70 billion, and more than double the membership base — 523,938 members against AMP's 219,095 — despite offering fewer funds to choose from.
On returns, AMP's disclosed average 5-year figure is 6.47%, against Westpac's 3.87%, though this reflects averages across each provider's full fund range rather than a like-for-like comparison of single funds with similar risk profiles. Neither provider's snapshot includes a five-year return figure for its top fund by this dataset (AMP's Milford Active Growth Fund and Westpac's High Growth Fund both show no comparable figure), so return comparisons at the individual fund level cannot be drawn from this data.
Both operate a single KiwiSaver scheme rather than multiple trust structures. Figures are drawn from FMA Disclose data and provider Quarterly Fund Updates; verify against the latest QFU before relying on any of this.

Reading the data: which provider suits which investor
Lower headline fees: Westpac (0.45% 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 Westpac (3.87%). 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 Westpac (or back)
- Decide the destination fund. Pick the specific Westpac 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. For full step-by-step provider-switch instructions including the eligibility letter and bank-transfer mechanics, see how to switch KiwiSaver provider.
