Smartshares, a unit of NZX, is planning to launch three new exchange-traded funds targeting global equities, bonds and possibly the New Zealand energy sector.

Smartshares currently has five ETFs on issue invested in baskets of large and medium-sized stocks on the NZX and ASX. They have a combined $NZ330 million ($A286.72 million) of funds under management, with the largest being the smartFONZ fund, which tracks the performance of the NZX 50 Portfolio Index.

"We're having a big push at the moment and are looking at launching three new ETFs in the next few months," said Sam Stanley, head of Smartshares.

He said two would cover global equities and bonds while the third would be sector specific.

"Looking at Mighty River Power, do you say I'll put $NZ100,000 into MRP or an energy ETF that covers the whole energy sector," he said.

Mr Stanley says ETFs provide an alternative investment option for people looking for low-fee savings. They are a retail product "that should also be in KiwiSaver funds".

The company charges a management fee of 0.6 per cent on its smartTENZ fund and its SmartOZZY fund, while the smartFONZ, smartMIDZ and smartMOZY funds attract a 0.75 per cent fee.
