Act's David Seymour says a unit for verifying the costs of pre-election political policy promises - would add more bureaucracy. 

Act and New Zealand First torpedoed a proposal by Finance Minister Nicola Willis to publicly fund such a service. 

National declined Labour’s offer of support. 

Seymour claims his Party managed to release a fully costed alternative Budget without it. 

He says he doesn't like the idea that people need bureaucracy to tell them what is good or accurate.
