NZX chief executive Tim Bennett will leave the stock exchange operator at the end of 2016, a year earlier than envisaged when he joined the company.
Bennett will end a four-year tenure in charge of NZX on December 31 to allow for a new chief to start at the beginning of the financial year, the Wellington-based company said in a statement.
Under his watch, NZX oversaw a jump in listings that coincided with the government's partial privatisation programme, the expansion of a suite of derivative products, and the acquisition of SuperLife and Apteryx to boost the stock exchange's funds management business.
"Tim's original employment agreements envisaged a five-year commitment to NZX," chairman James Miller said.
"With Tim indicating a desire to step down and in order to ensure an orderly succession, the board started a conversation with Tim on how to best manage that transition, and today's announcement clears the way for the board to search for a new CEO."
Bennett replaced Mark Weldon in 2012 who had been in charge of NZX for a decade. Weldon oversaw a series of acquisitions that boosted the value of the stock exchange operator, though that included the Clear Grain Exchange which has been the subject of drawn-out litigation between NZX and its Australian vendors.
