About “—” in return figures: it means no figure is held, not a return of zero. Of the 2 funds listed, 1 has a 1-year return. Figures are drawn from fund disclosures on the FMA Disclose register, chiefly quarterly fund updates. Each fund shows the most recent figure held; the latest quarter broadly covered across all funds is March 2026. A fund too new to report a period has no figure for it; other gaps are figures not yet captured from the updates ingested so far.
Data sourced from each scheme's most recent FMA-filed Quarterly Fund Update. Past performance is not a reliable indicator of future returns.
The transfer process
- Pick the receiving fund at Booster. The receiving provider needs the specific fund choice, not just the scheme. View Booster's line-up at /providers/booster.
- Apply to Booster. Most providers offer online application. They will ask for your IRD number and the name of your current scheme (BNZ).
- Booster initiates the transfer. The receiving scheme contacts BNZ and arranges the inter-scheme transfer. Under the KiwiSaver Act this is free of charge to you.
- Your balance moves over 2-3 weeks. BNZ sells your existing units, transfers the cash, and Booster buys units in your chosen fund. You are typically in cash for a few business days during this window.
- Your employer is notified automatically. IRD receives the new scheme details and routes future contributions accordingly. No paperwork required on your side.
