Weighted average of advertised standard floating first-mortgage rates for new housing customers (B3, INR.MBI06.F). Current: 6.07% for 31 Jul 2026. Monthly survey; specials and fixed terms are excluded.
From 29 Feb 1964 to 31 Jul 2026 (750 months): mean 9.35%, median 8.16%; low 4.37% (31 May 2021), high 20.50% (30 Jun 1987). An official benchmark, not a quote for your loan.
New Zealand's floating first-mortgage rate is a retail lending benchmark, not a policy rate. The figure comes from the Reserve Bank's B3 retail interest-rate survey, series INR.MBI06.F, and is a weighted average of the advertised standard floating rates offered to new housing customers. It is compiled monthly, so the headline is the latest survey month rather than a live quote, and advertised specials, fixed terms and discounts negotiated with individual borrowers are excluded. A central-bank survey average is a reference for the market, not an offer you can accept.
The chart plots the monthly survey history; the table repeats it as numbers in reverse order. The "versus the previous reading" line compares the latest month with the month before, and the mean, median, low and high describe the whole run shown. Range buttons shorten the window without recalculating anything, and Chart and Table are two views of one series. Because this is a survey average, it trails changes in wholesale funding costs and the OCR, and it can move when banks reprice rather than when the official rate changes.
About this desk
The United Kingdom desk leads with Bank Rate, the Bank of England's policy rate, then SONIA, the sterling overnight market benchmark the Bank publishes but does not set. Euro-area, US, Canadian and Australian rates follow, with the rest of the build's series after them. All desks republish the same official series; this desk only reorders the menu and the wording, so the figures do not change when you switch desks.
Both UK series come from Bank of England statistical tables and are republished under the Bank's open-data terms, with attribution. Bank Rate is a policy setting that moves at MPC decisions; SONIA is a transaction-based market rate that moves daily. The build does not publish a UK retail mortgage or savings rate, because no such official series is ingested here — those pages are absent rather than estimated. This is not financial advice.
