Quality

Dissemination of documentation on methodology and sources used in preparing statistics

See the Survey template and definitions.

Dissemination of statistics that support statistical cross-check and provide assurance of reasonableness

The Reserve Bank publishes data on the weighted floating first mortgage new customer housing rate in the Retail interest rates on lending and deposits (B3).

Interest.co.nz publishes mortgage interest rates for a range of terms.

New customer average rate

The interest rates recorded here are simple averages of the advertised (or ‘carded’), standard, first mortgage interest rates offered by banks to new borrowers for residential property. Any special rates or discounts offered to borrowers with conditions (e.g. 30 percent equity) are excluded from the results.

Some banks offer standard rates at terms other than those currently published (e.g. 18-month fixed rate or greater than 5 years) The RBNZ plans to make a wider range of rates available later this year when a longer series is established.

Please note that the same floating interest rate source is published as a weighted average advertised rate for standard first mortgage interest rate borrowers in the B3 web table compared to a simple average in B20 – so the two rates will not necessarily align.
