ASB's cash profits rose 12 per cent in the six months to December 31 to $393 million - breaking another record for the bank.
The bank's loan book grew from $55.5 billion to $59.3 billion despite the Reserve Bank's clamp down on home lending which kicked in from October last year.
Deposits also rose from $39.9 billion to $43.7 billion.
