Two of New Zealand's biggest banks have imposed new restrictions on overseas property buyers.
In a statement, Westpac said it would no longer lend to non-resident borrowers with overseas income, while the maximum allowed loan-to-value ratio for New Zealand citizens and permanent residents with overseas income would be reduced to 70 per cent from 85 per cent.
Borrowers who are on temporary residence visas will only be accepted if they have both a New Zealand address and a New Zealand income.
Westpac said the changes were imposed as part of an "ongoing review of lending criteria in a fast moving market". It added that verification of foreign applications was essential to meet its lending criteria "but is operationally difficult in these cases".
The changes are effective immediately.
