Ruthanasia, a portmanteau of "Ruth" and "euthanasia", is the pejorative name (typically used by opponents) given to the period of free-market economic reform conducted during the first term of the fourth National government in New Zealand, from 1990 to 1993. As the first period of reform from 1984 to 1990 was known as Rogernomics after the Labour Party Minister of Finance, Roger Douglas, so the second period became known as "Ruthanasia", after the National Party's Minister of Finance, Ruth Richardson.
