The Government is scrapping 120 redundant laws, ranging from the Rugby World Cup 2011 legislation to laws providing funding for royal visits.
The laws were now superfluous, Regulatory Reform Minister Steven Joyce said, and the tidy up would remove about one tenth of the legislation on the books.
He and Act leader David Seymour are doing the purge as part of Act's confidence and supply agreement which included a Productivity Commission aimed at removing red tape.
Many of the laws in question give an overview of New Zealand's history. They include authorisation to fund a post-war visit by King George VI and Queen Elizabeth, the Queen Mother in the late 1940s - a visit that never went ahead because the King fell ill and later died in 1952.
Another was special legislation for relief funding after the 1931 Hawkes Bay earthquake.
Others included a 1978 law dissolving the National Airways Corporation after it merged with Air New Zealand, and a 1987 law to abolish the Tobacco Board.
