Public servants jumping roles may have melted the Government's pay freeze.

The policy that was introduced for high-paid public servants during the Covid-19 pandemic has now ended.

New Zealand Initiative Chief Economist Eric Crampton told Mike Hosking people have been moving to different ministries to get a pay increase.

He says that leads to a denigration of expertise within any ministry.
