"We're not making individual stock selections by any stretch of the imagination and we don't intend to be an active manager," Bennett said. "We are going to run this as quite a separate business - we are in the process of hiring someone to run it. It's based in Auckland, not in our office, and will continue to be for some time. We'll separate that out to ensure there is no perception of conflict or different objectives between different parts of the business."
In 2011, the Financial Markets Authority warned SuperLife over some of its sales practices. Bennett said he couldn't comment specifically on trading practices, but the goal of NZX was to building "a low cost, competitive Kiwisaver ETF fund offering".
NZX expects to launch its new growth market, NXT, which targets small-to-medium sized businesses with a lower disclosure threshold, early next year. Once the market has enough liquidity, the stock market operator would offer NXT-based ETF's too, Bennett said.
NZX will pay $20 million up front for SuperLife, of which $10 million will be in cash and $10 million in shares, which it expects to complete in mid-January. It will pay a further $15 million over the next three years if the business hits retention and growth of funds under management targets, of which $5 million will be in shares and $10 million in cash.
Separately, NZX also gave an update on its employment litigation with the Clear Grain Exchange developer Ralec, saying a trial date isn't expected before the end of 2015 and that it expects to pursue a number of interlocutory matters. It also said it is in talks with the Inland Revenue Department over proposed adjustments to historic matters that may have a tax impact of about $1.3 million, though the outcome is still uncertain.
Shares of NZX were unchanged at $1.22, and have slipped 1.6 percent this year. The stock is rated an average 'hold' based on three analyst recommendations compiled by Reuters, with a median price target of $1.29.
