NAB is cutting the discount it offers new mortgage customers, effectively raising their home loan rate.
The lender remains the only one of the big four not to impose an out-of-cycle standard variable rate rise on customers, but it will from Friday reduce the discount it is prepared to give new customers from 0.48 to 0.30 percentage points.
The rate on offer to new principal and interest borrowers will rise from 3.69 per cent to 3.87 per cent.
Existing customers will be unaffected, with the old discount still on offer and NAB's standard variable rate unchanged at 5.24 per cent.
NAB said in September it would keep rates on hold in a bid to build loyalty and as an acknowledgement of the need to rebuild trust following revelations of misconduct aired at the royal commission.
Chief executive Andrew Thorburn said that focus had not shifted.
"We value our existing customers," Mr Thorburn said in a statement.
"We've got almost a million home loan customers at NAB, and we're signalling to them that we appreciate your loyalty, we appreciate your business, and we want to keep this rate on hold for as long as we can to acknowledge that."
The bank's full-year profit, revealed last week, dropped 14.2 per cent to $5.7 billion after large expenditure on restructuring and customer remediation.
