Kiwibank has become the third bank to lift its mortgage rates in a week.
Kiwibank said from today it would increase its one year home loan rate from 5.25 per cent to 5.45 per cent while its two year rate would increase from 5.65 per cent to 5.95 per cent for borrowers with at least 20 per cent equity.
Borrowers with less than 20 per cent equity will have to pay 6.29 per cent per annum for the two year fixed rate.
Kiwibank said it had lifted rates because of increased costs.
"The changes have been made as a result of increased costs of wholesale funding," the bank said in a statement.
