Government agency the Energy Efficiency and Conservation Authority awarded THL a $402,000 grant to accelerate the availability of electric motorhomes, invest in charging equipment and develop itineraries with charging stations at certain intervals along the way.
The company is developing itineraries on a minimum 150km range.
Chief executive Grant Webster said his company was working with the Holiday Park Association and hopes to see charging stations in several parks over the coming months with a rapid expansion over the next few years.
The speed of production depended on the speed of the charging.
"Once we have the model right, the pricing right and we are happy the infrastructure in New Zealand can support it, we will be able to plan larger scale production."
Travellers will be able to charge e-RVs in a number of ways including overnight chargers, fast charging with a five minute to 30-minute top up and shorter interim top-ups of one to two hours at popular tourist destinations such as the Waitomo Glow Worm Caves.
The company says the e-RV itineraries were an opportunity for the regions and those who have invested in charging infrastructure - guiding travellers throughout the country - rather than just the main tourist centres.
