A funding boost and plans to expand the Aquavan programme mean it will be used to educate even more groups this year.
Last year, the Aquavan went to schools and catchment groups and was used to teach people about how the marine environment could be affected by what happened on farms.
The Aquavan has been part of the New Zealand Marine Studies Centre in Dunedin for just over a year.
It was designed as a way to transport animals and continue research and teaching about marine life after the aquarium at the centre closed down.
Specially designed to transport marine species, the van is equipped with chilled recirculating seawater tanks.
