The listing of Mighty River Power and developments in Fonterra's share trading are expected to provide even more of a boost to the NZX and capital markets this year.
Shares in the stock market operator surged almost 7% on Monday after it lifted its full-year profit by more than half to $14.5 million.
Revenue rose 11% to $55.6 million with the NZX's information, markets and infrastructure arms all growing.
NZX's outgoing chief executive Mark Weldon says despite the challenging global environment, he expects that balanced growth to continue throughout 2012.
Mr Weldon says the signs are already positive, with average daily trades in the cash equities market at more than 3100 this year compared to 2200 last year.
The NZX's dairy futures market experienced significant growth last year and its grain exchange is meeting its targets.
Mr Weldon also expects the NZX's focus on commodities to continue to pay off this year.
The NZX plans to return $32.5 - $35 million to shareholders by cancelling about 10% of its shares before the end of May. Its stock will then be split on a 7 for 3 basis.
Shares in NZX rose 18 cents to $2.77 on Monday.
