The Government has been quizzed on why it's not putting money into a renewable electricity scheme.

It has partnered with worldwide asset management company BlackRock to launch a $2 billion infrastructure fund.

It'll have a particular focus on the path to 100 percent renewable energy, such as solar, wind and green hydro.

Energy Minister Megan Woods says they're acting in New Zealand's interests.

"One of the jobs of Government and of ministers is to work actively to bring overseas investments to New Zealand, and that's exactly what we've been doing."
