Profit at NZX has increased by 17% despite plummeting share prices and extreme volatility in the stock market.
Profit was almost $10.2 million in the year to December, compared to $8.7 million the previous year. The stock market's value fell by 34% in the same period.
Chief executive Mark Weldon says the result can be attributed to the success of its businesses not related to the exchange.
Profit at the Australian Stock Exchange last year was down by 8%, Singapore by 37% and Malaysia by 57%.
