More public sector roles face the chopping block, following recent announcements.

The Ministry of Health is the latest to propose slashing jobs in order to meet the Government's cost-cutting targets- of an average of 6.5 percent.

Former United Future leader Peter Dunne says there needs to be a purpose for restructuring the sector beyond cutting jobs.

"It's pretty easy to say- let's just cut numbers. But you've got to have a purpose for doing so other than saving money."
