Infometrics' Principal Economist says the Government's not entirely ignoring the lack of budget funding allocated for lifting KiwiSaver employer contributions. 

The Greens say the Government hasn't accounted for the cost to public services, which could cost more than $700 hundred million. 

Finance Minister Nicola Willis says that's being worked on - and will be in next year's Budget. 

Brad Olsen says the hole wasn't costed, but hasn't been forgotten. 

"There is a cost - it will have to be met, but it's not being directly disclosed in the Budget figures."
