In the early nineties, maverick National Party MP Winston Peters also came to oppose New Right economic policies, and led his elderly voting bloc out of the National Party. As a result, his New Zealand First anti-monetarist party has been a partner in coalition governments led by both National (1996–98) and Labour (2005–08 and 2017–20). Due to the introduction of the MMP electoral system, a New Right "Association of Consumers and Taxpayers" party, known as ACT New Zealand, was formed by ex-Labour New Right-aligned Cabinet Ministers like Richard Prebble and others, and maintaining existing New Right policy initiatives such as the Employment Contracts Act, while also introducing US-style "welfare reform." ACT New Zealand aspired to become National's centre-right coalition partner, but has been hampered by lack of party unity and populist leadership that often lacked strategic direction.
