David Seymour says he sees no reason why a potential coalition deal shouldn't be made public.
Arrangements in 2017 weren't publicly released, when the Chief Ombudsman ruled details couldn't be requested under the Official Information Act - because it came within Jacinda Ardern's capacity as Labour leader.
But ACT Party leader Seymour says he'd be happy for this year's finalised arrangement to be in the open.
"We're really happy with the way it's going, I mean, we've been chatting through the different challenges that we think the Government will face."
Prime Minister-Elect Chris Luxon isn't ruling out it out.
