The accounts show various measures of revenue and profit, a familiar theme for banks nowadays.
But the income statement summary shows total operating income rose 13.8% to $2.43billion in the year from $2.1billion in the previous corresponding period.
Operating profit rose nearly 27% to $1.57billion from $1.23billon and the reported profit attributable to BNZ shareholders rose 22.1% to $1.04billion.
Cash earnings, the current favourite measure of banks, rose 2% to $823million from $807million in the pcp.
BNZ chief executive Anthony Healy said the result demonstrated the underlying strength of the bank and its resolve to deliver in a testing and competitive year.
''It's also been a year of building foundations. We've made bold strategic decisions and investments that will set us up for success in future years. I've never been more proud of our people and what they've achieved.''
In his divisional report, Mr Healy said BNZ had a continued focus on supporting its agribusiness customers, who were dealing with volatile commodity prices.
The bank had taken a conservative through-the-cycle approach to the dairy industry, with an economic cycle adjustment to its collective provisions to recognise a period of lower and more volatile dairy prices.
Asset quality in the agriculture and dairy books remained sound.
''We are well placed to continue supporting our farming customers through a more volatile period. They've been through these cycles before and their BNZ partners are well placed to support them with good advice.''
The bank re-entered the broker market as borrower preference for brokers had increased, especially in Auckland, he said.
BNZ had only been back with brokers four months and had already exceeded its targets.
It was now building capability and resource in its own broker hub to meet the growing demand.
The primary focus in housing had been to expand the BNZ presence in Auckland.
It had already accredited 197 brokers and hired more than 30 additional mobile bankers.
Small business had always been integral for BNZ, as it was to the New Zealand economy, Mr Healy said.
During the year, BNZ had recruited more than 50 small business bankers, including 20 in Hamilton, 12 in Christchurch and 20 in Auckland.
The decrease in the market share for credit cards was largely due to customer losses flowing from the departure from GlobalPlus, he said.
The new card and rewards programme, BNZ Advantage, was resonating well with customers.
Mr Healy said BNZ maintained a robust capital structure and a strong balance sheet.
At balance date, BNZ had $86.8billion in total assets, up from $79.7 billion in the pcp.
Total liabilities rose to $79.7 billion from $74 billion in the pcp. Shareholders' equity at balance date was $7.04billion from $5.7billion in the pcp.
National Australia Bank, Australia's top lender by assets and owner of BNZ, announced a 15.5% rise in annual profit and announced it would spin off and sell its under-performing UK operations through an initial public offering early in 2016.
The British business, which has been plagued by bad debts and misconduct charges, has long been a thorn on NAB's side, dragging returns and net profits for the group.
NAB said it was forced to set aside $A1billion ($NZ1.06billion) for the year-ending September 2015 to cover the British business against charges relating to the mis-selling of loan insurance to individuals and hedging products to small businesses.
NAB, which has long trailed its three main rivals on earnings growth and shareholder returns, made withdrawing from offshore and low-returning businesses a priority under chief executive Andrew Thorburn who took the helm in August.
About 75% of Clydesdale Bank shares would be offered to NAB shareholders while 25% would be sold in an initial public offering, the bank said.
Under Mr Thorburn, NAB has left the United States and was ahead of its rivals in raising $A5.5billion capital to meet tighter regulatory requirements. Yesterday, it also confirmed sale of 80% of its insurance unit to Japan's Nippon Life Insurance.
Annual cash profit, which excluded one-offs and non-cash accounting items, rose to $A5.84billion for the 12 months to September from $A5.2billion in the pcp. Earnings missed expectations because of higher charges related to its UK business.
