Smartshares chief executive, Hugh Stevens, said the two thematic funds were chosen because they thought they would be the most appealing to New Zealand investors.
"Our feeling was that we wanted to focus on two that would really capture the imagination of New Zealand investors and I think in New Zealand we are a very high tech early adopter nation," he told BusinessDesk.
The automation and robotics ETF will give investors exposure to artificial intelligence and e-commerce logistics while the healthcare ETF will tap into areas such as personalised medicine and immunotherapy.
There were a smattering of trades in the funds shortly after the bell was rung and Stevens expects trading to ramp up, given the strong pre-registration interest over the past week or so.
"It's a growing market and what we have seen from the expressions of interest is that there is a core group of early adopters and then we will just see steady growth," he said.
"Later in the day, we'll see the trades coming in from the nominees and over the next few days people will get stocks and tickers set up in their trading system," he added. Sharesies, for example, added the eight new funds to its platform.
NZX-owned Smartshares partnered with BlackRock to offer the funds.
Christian Obrist, BlackRock's head of iShares Australia, said New Zealand is a "very progressive" market for ETFs and "it's all about bringing more choice to the investors base."
He said launching the funds locally would have been a major effort, "so it makes more sense for us to partner and collaborate with Smartshares to bring our product to the market." iShares has around US$1.9 trillion in assets under management.
Smartshares is New Zealand's only issuer of ETFs listed on the NZX Main Board and across six registered schemes manages over $3.2 billion. It launched New Zealand's first ETF in 1996.
