The National Party says it would seek further cost savings from the public service of almost a quarter of a billion dollars a year, if re-elected.
The term of the National-led government was marked by job losses, consolidation of agencies and departments and trimming of back room costs.
National's state services spokesperson Tony Ryall told TV3's The Nation programme on Saturday there are still savings that can be made.
Mr Ryall says if government departments spending more than the average were to reduce their budgets to the average, it would save the next government $240 million a year.
He says if every department spent as little as those which spent the least, the next government could save more than $400 million a year.
