The extent to which they dominate the banking sector can be seen in profits: In the 2012/2013 financial year, the largest of the Big Banks, ANZ New Zealand, made a profit of NZ$1.37 billion. The smallest, BNZ, made a profit of NZ$695 million. State-owned Kiwibank, community trust-owned TSB Bank, SBS Bank (formerly Southland Building Society) and Heartland Bank, the next four largest banks by profit, made NZ$97 million, NZ$73.5 million, NZ$14 million and NZ$7 million (albeit with an underlying result of about NZ$30 million) respectively.
