TSB Bank has posted a record profit for the six months to the end of September.
It made a profit after tax of $29.2 million - the highest in the bank's history.
Its loan book grew by more than 10% to just over $2.2 billion. TSB also has $3.69 billion worth of funds on deposit, up nearly 20% on a year ago.
Chief executive Kevin Rimmington says the bank has been insulated from the credit crisis because it is 100% New Zealand owned.
He says 70% of its growth is from outside Taranaki, where the bank is based.
