ASB has cut its three- to five-year fixed mortgage rates by between 20 and 30 basis points, bringing its three-year rate down to 5.29% from 5.49%.

The bank increased shorter-term rates, lifting its six-month fixed rate by 20 basis points and its 18-month rate by 14 basis points. One-year and two-year rates remain at 4.65% and 5.25% respectively.

ASB also reduced term deposit rates for two- to five-year terms, with reductions reaching as high as 25 basis points. Executive general manager personal banking Adam Boyd said the changes reflect recent movements in wholesale interest rates.
