After 1951 the National Government continued its policy of deregulating the economy by ending rationing on basic food commodities, loosening import controls, and encouraging home ownership by selling states houses to their tenants. Shortly after being re-elected, the government also enacted the Police Offences Bill which gave the police substantial powers to deal with future industrial unrest. Holland's Government also reformed the superannuation scheme to enable retiring public servants to claim a portion of their entitlement as a lump sum payment. In addition, the Government established producer-controlled agricultural boards. Despite its center-right orientation, the National Government maintained the previous Labour Government's policies of full employment and the welfare state. While the 1950s was a boom time for New Zealand and other Western economies, inflation remained a problem.
