SBS Bank's $14.1million surplus before tax for its half-year trading to September repeated last year's then record profit, with total operating income up $4.4million, year on year.
SBS, which this week rebranded itself, reported a 21% increase in lending advances to $469million, with retail deposits from customers growing $173million and wholesale funding increasing $125million over the previous year.
Chief financial officer Tim Loan said in a statement the loans increase to customers had been geographically spread across New Zealand.
''This strong result reflects growing market share across the country and a healthy increase in member numbers.''
Total operating expenses increased $3.5million because of heavy investment in core systems and infrastructure projects, he said.
With SBS having gained a ''positive outlook'' by international rating agency Fitch Ratings, SBS was ''in a good position to have a solid financial year'', Mr Loan said.
