The new Tongariro Whanganui Taranaki (TWT) Conservancy has existed for two years, and the Taranaki/Whanganui board oversees planning in its southern and western end. The other end has a Tongariro/Taupo board, also of 10 people and with five vacancies.
The boards each meet quarterly, and have a combined meeting once a year. Their chairpeople also attend each other's meetings.
The two-board arrangement was working well for the large conservancy so far, TWT community support manager Mark Davies said.
"We're still learning about the new conservancy and how best to connect to communities of interest that the boards represent. We would only change if it wasn't delivering on the outcomes we want."
The large number of vacancies were an opportunity for keen conservationists to step up, he said.
Nominations close on January 25, and appointments begin from July 1 and last three years. Information and nomination forms can be found at www.conservationboards.org.nz.
