ASB Review.

ASB Bank — NZ Mortgage Review (2026)

ASB Bank is one of New Zealand's largest registered banks, owned by Commonwealth Bank of Australia. For New Zealand borrowers, the lender's specialties include owner-occupier, first home buyers, KiwiSaver, business banking, investor lending. As an independent NZ mortgage broker, Finch arranges loans through ASB alongside the full panel of registered NZ banks (ANZ, ASB, BNZ, Westpac, Kiwibank, TSB, SBS, The Co-operative Bank, Heartland) and the specialist non-bank market — so we can recommend ASB only when their offer genuinely beats the alternatives for your scenario.

Who ASB Suits Best

ASB suits first home buyers and clean-PAYE borrowers wanting efficient main-bank lending. We see strongest outcomes when the client's income profile, deposit position, and intended property align with ASB's current scorecard. Outside those scenarios, another NZ lender will usually price sharper or move faster — which is why we compare every option before recommending.

ASB — Strengths

• Highly efficient digital application and decisioning
• Strong first home buyer policies and Welcome Home Loan participation in some scenarios
• Competitive carded and broker rates
• Active cashback contributions for refinance and purchase

ASB — Considerations

• Test rate runs at the higher end of the main-bank range
• Investor LVR policies are conservative
• Less appetite for complex self-employed scenarios

How ASB Compares Across the NZ Lender Panel

No single NZ lender wins for every scenario. Pricing varies by week and by deal type — ASB may be sharpest one month and uncompetitive the next, while a non-bank like Resimac or Pepper Money picks up cases the main banks decline. Use our live NZ rates comparison to see where ASB sits today, then book a free consultation to match your scenario against the full panel.

Documents ASB Typically Requires

• 3 months payslips (PAYE) or 2 years accountant-signed financials (self-employed)
• 3 months bank statements across every account including credit cards
• KiwiSaver provider statement and annual summary (for first home buyers)
• NZ photo ID + proof of address (AML compliance)
• Evidence of deposit and recent savings history

Service Coverage Across NZ

Should You Go Direct, or Use a Broker?

Going direct to ASB only gives you ASB. Using Finch costs you nothing — ASB (where they're the right answer) pays the broker fee on settlement, not you — and you get the comparison across every other NZ lender for free. Read our real NZ client case studies for examples.
