ANZ has suffered a couple of regulatory blows this month with the Reserve Bank forcing it to hold more capital against housing and farm lending from June 30 and to use the standardised model for calculating its operational risk capital rather than its own internal model.
That's because it had been using its internal model for calculating ORC since December 2014 without first getting RBNZ approval.
The ORC measure was one of about 45 internal models ANZ uses and it can continue to use the other 44.
Only the four major banks, which are all owned by Australia's major four banks, are allowed to use their own internal models to calculate capital.
In February, RBNZ revealed that ANZ needed only slightly more than half the capital that the government-owned Kiwibank needs to back each $100 of mortgage lending because of the advantage it gains from using internal models.
Kiwibank, along with all the New Zealand-owned banks, is required to use standardised models.
Also earlier this month, ANZ reported net profit for the six months ended March fell to $929 million from $964 million in the same six months a year earlier.
