Confusing partisan debates around political party policies could soon be a thing of the past after Cabinet gave the green light to the creation of a new policy costing unit.
Finance Minister Grant Robertson said ministers have recommended an independent Parliamentary Budget Office (PBO) be set up to cost party policies before elections.
Such an entity was in the Labour/Green Party confidence and supply agreement.
But the PBO would not be established until 2021, meaning it would not be in place before next year's election.
Robertson said it would have been ideal to have it set up sooner, but the Government was "taking the time to get this right".
