New charging stations for electric vehicles have been opened in Nelson, Thames and Auckland.
Transport Minister Simon Bridges says New Zealand started with one charging station, in Northland, in May 2014.
"Just over two years later we have more than 30 public fast charging stations and that number is growing by the week," he said.
"More than 100 other charging stations have also opened up around the country."
Mr Bridges says the cheapest and easiest way to charge an electric vehicle is overnight at home, but having public charging stations means EVs can be used for longer distances.
The Government has a target of 64,000 EVs on the roads by 2021.
