ASB has launched a new "limited time" two-year fixed home loan rate of 5.70 per cent.
The special rate, which came into effect at 5pm on Friday, is 25 basis points lower than the bank's standard rate.
"It comes at a time when we're noticing more customers seeking to split their home loan across a variety of terms, meaning they can take advantage of great short-term rates mixed with some long-term certainty," said spokesman Shaun Drylie.
ASB also has a special six-month rate of 4.75 per cent running at the moment.
To qualify for the two-year and six-month mortgage rates, buyers must have at least a 20 per cent deposit, (a Loan to Valuation Ratio of less than or equal to 80 per cent), an ASB credit card, and an active transactional account.
