ACT's leader says now is a good time for the Government to think about its organisation.

David Seymour wants a limit on Cabinet Minister numbers - with none outside Cabinet, and only one associate minister for finance.

Seymour says there are currently ministers with seven different departments, and departments answering to 19 ministers. 

He says he doesn't expect change pre-election - but believes Chris Luxon gets his viewpoint.

"Chris cut his teeth as a manager - and I'm sure that it's something that, without speaking for him, he will intuitively get."
