The Better NZ Trust has written to National's leader, Christopher Luxon, imploring him not to scrap the clean car discount.
The Party listed scrapping the so-called 'ute tax' in its 100-day plan before the election.
But the Trust says New Zealanders will buy fewer new EVs as a result, and that will slow our transport emissions reductions.
Trust members are mostly electric vehicle drivers and advocates hoping to accelerate the shift to EVs in Aotearoa.
Better NZ Trust spokesperson Rob Birnie spoke to Ingrid Hipkiss.
