Lianne Dalziel

In late February 2020, the New Zealand Police referred Dalziel's election expenses during the 2019 Christchurch mayoral election to the Serious Fraud Office. Two complainants, including rival mayoral candidate John Minto, had filed a complaint regarding donations by six people that exceeded the $1,500 limit under the Local Electoral Act.

Following months of speculation, The Press reported on 20 April 2013 that Lianne Dalziel would challenge Parker for the mayoralty, and that she had asked 24-year-old Student Volunteer Army organiser Sam Johnson to be her running mate, with a view of Johnson becoming deputy mayor. The newspaper expressed surprise by this pairing, given that Dalziel was a Labour Party member, and Johnson a member of the Young Nats, the youth arm of the National Party. Saying that: "It was a really difficult decision to make, but I don't think it is the right thing for me right now", Johnson eventually decided against running. On 19 June, Dalziel formally confirmed that she would contest the mayoralty, also announcing that she would resign from Parliament, which would trigger a by-election in the Christchurch East electorate. Dalziel delivered her resignation letter on 17 September and delivered her valedictory speech the following day with her resignation taking effect on Friday, 11 October; the day before the local body election so that the by-election campaign did not interfere with the local body election. In a later interview, Dalziel confirmed that she would have left Parliament even if Shearer had put her onto the front bench.

Dalziel was elected Mayor of Christchurch in the October 2013 mayoral election, with a margin of almost 50,000 votes over the next candidate, businessman Paul Lonsdale. She was sworn in on 24 October, with a past mayor, Vicki Buck as her deputy. At the 2019 local election, she won the mayoralty for a third time.

Rumours of Dalziel standing as Mayor of Christchurch go back to at least 2009. Since the February 2011 earthquake, the rumours that Dalziel would contest the 2013 Christchurch mayoralty became more consistent. In May 2012, Dalziel tried to put an end to these rumours by announcing: "The job I really want is Gerry Brownlee's, rather than Bob Parker's." Brownlee is Earthquake Recovery Minister, and Parker was the Mayor of Christchurch at the time. In the February 2013 reshuffle of opposition portfolios, Dalziel dropped out of the top 20 (only the first 20 positions are ranked by the Labour Party). An editorial in The Press presumed that her strong support for David Cunliffe was part of the reason for her demotion. The editorial also speculated that she might reconsider her political future:

After Labour was defeated in the 2008 general election, Dalziel became the Opposition spokesperson on Justice and Commerce and, from 2011, the spokesperson for the Christchurch Earthquake Recovery, Civil Defence & Emergence Management, Consumer Rights & Standards, and associate spokesperson for Justice.

After the 2005 election, Dalziel was re-elected by her caucus colleagues to Cabinet and was given the portfolios of Commerce, Small Business, and Women's Affairs.

In the new government formed by Labour, Dalziel became Minister of Immigration, Minister for Senior Citizens, and Minister for Disability Issues. When Labour won re-election in the 2002 election, Dalziel also became Minister of Commerce (while ceasing to be Minister for Disability Issues). In 2003, she ceased to be Minister for Senior Citizens. As Minister of Immigration, Dalziel was often in the spotlight. In particular, she often clashed with Winston Peters, leader of the anti-immigration New Zealand First party.

Mike Williams, President of the Labour Party from 2000 to 2009, states that he was surprised by Clark appointing Dalziel Minister of Commerce and thought of it as an "odd choice". But she worked herself into the portfolio, paid attention to detail, and within a year had "proved herself". Williams believes this is due to her high intelligence and her ability to listen. Tim Barnett, MP for Christchurch Central from 1996 to 2008, and today General Secretary of the Labour Party (equivalent to CEO), credits her training as a lawyer and "having a bigger brain than most of us" for her success. Williams states that as Minister of Commerce, Dalziel worked closely with National's Simon Power and built "cross-party unity on various issues".

Time magazine picked her as a future leader in its December 1994 edition.

Dalziel entered Parliament as a Labour Party MP for Christchurch Central in 1990, replacing outgoing former Prime Minister Geoffrey Palmer. She held this seat until the 1996 election (being replaced by Tim Barnett), when she became a list MP under the new MMP electoral system. In the 1999 election, she chose to contest an electorate again, and won the Christchurch East seat. She held the seat in the 2002, 2005, 2008 and 2011 elections. In 2011 she opted not to go on the Labour list.

Lianne Audrey Dalziel (/d æ l ˈ z ɛ l / ; born 7 June 1960) is New Zealand politician and the current Mayor of Christchurch. Prior to this position, she was a member of the New Zealand Parliament for 23 years, serving as Minister of Immigration, Commerce, Minister of Food Safety and Associate Minister of Justice in the Fifth Labour Government. She resigned from Cabinet on 20 February 2004 after apparently lying about a leak of documents to the media, but was reinstated as a Minister following Labour's return to office after the 2005 election. She resigned from Parliament effective 11 October 2013 to contest the Christchurch mayoral election. The incumbent, Bob Parker, decided not to stand again, and she was widely regarded as the top favourite and won with a wide margin to become the 46th Mayor of Christchurch.

Dalziel was born in 1960 raised in Christchurch, and attended Canterbury University. She graduated with a law degree and was admitted to the Bar. She served as the legal officer for the Canterbury Hotel and Hospital Workers' Union, and later became the union's Secretary. She also participated in national groups such as the Federation of Labour and the New Zealand Council of Trade Unions.
