defeated Carter to win Banks Peninsula. She has remained the MP for the area (later renamed Port Hills) since that time, holding the seat until her retirement in 2020. Dyson was a senior member of the Labour Party during the Helen Clark-led Fifth Labour Government, serving in a range of health and employment-related portfolios including Minister for Disability Issues (1999–2000; 2001–2008), Minister for ACC (2002–2007), Minister of Labour (2005–2007) and Minister for Social Development and Employment (2007–2008). Fifth Labour Government, 1999–2008 When the Labour Party won power in the 1999 general election, Dyson was appointed to a number of minor ministerial roles, including Disability Issues and Associate Health and Associate Social Development. However, she resigned them on 31 October 2000 after being caught drink driving. She regained most of her ministerial responsibilities on 4 June 2001. She acknowledged after her resignation that she had been convicted and fined for possession of cannabis when she was a teenager stating "I find it sickening that some 25 years later someone has anonymously passed this information to journalists." As Minister for Disability Issues, she led the development of what would become the New Zealand Sign Language Act 2006, which gave New Zealand Sign Language the status of an official language of New Zealand. In her valedictory statement in 2020, Dyson reflected on the Act: "I regret that it wasn't more prescriptive in its implementation, because its roll-out has been slower than it could have been. That should be fixed." In a reshuffle on 31 October 2007, Dyson was promoted to Minister for Social Development, which she held until the Clark government lost power at the 2008 general election. Despite the swing against Labour at that election, Dyson won the new Port Hills electorate with an increased margin. Opposition, 2008–2017 The National Party won the 2008 election, putting Labour in Opposition where it would remain for the next nine years. During this time Dyson held a range of portfolios, including health (2008–2011), internal affairs (2011–2013), conservation and disability issues (2013–2015), Canterbury Earthquake Recovery (2013–2014) and senior citizens (2013–2017). She was also deputy chair of the Health select committee (2008–2011) and chair of the Government Administration select committee (2011–2017). In December 2009 Dyson's Resource Management (Requiring Authorities) Amendment Bill, which would amend the Resource Management Act 1991 to reintroduce a public interest test for projects seeking requiring authority, was drawn from the member's ballot.
