She said people are amazed at how much power an electric car has and how little power you need to run it.
"We had a few people today (Friday) have a test drive and as soon as they take off they have a surprised look on their face and are shocked at quick and smooth they are to drive."
The trip is being done in completion by three vehicles but Trounson said there had been a lot of people joining them on their journey.
"The entire trip we have had different people from different towns join us along the way for short stints and tomorrow when we head off we will have another eight EVs join us on our trip to Auckland, as we go along the coast up to Gisborne and Tauranga and across to Raglan."
Trounson has owned EVs for the last four years and said she has seen the value and quality of the vehicles improving year after year.
"Each year the cars are getting cheaper because the batteries are getting cheaper and more and more companies are focusing their resources into EV production."
The road trip is run by the Better NZ Trust and supported by the Energy and Efficiency Conservation Authority.
Better NZ is a charitable trust whose mandate is to create environmental, financial and health benefits for all Kiwis through education and by assisting in the adoption of zero carbon renewable technologies.
It is the biggest event on the trust's calendar.
