Tariana Turia

When debate about ownership of New Zealand's foreshore and seabed broke out in 2003, and the Labour Party proposed vesting ownership in the state, Turia voiced dissatisfaction. Along with many of her supporters in Te Tai Hauauru, she claimed that Labour's proposal amounted to an outright confiscation of Māori land. When it became publicly known that Turia might vote against Labour's bill in parliament, tensions between Turia and the Labour Party's leadership increased. The hierarchy strongly implied that if Turia did not support Labour policy, she could not retain her ministerial roles.

On 30 April 2004, after a considerable period of confusion about Turia's intentions, she announced that she would resign from parliament on 17 May. This precipitated a by-election being called in Te Tai Hauauru, which Turia contested as a member of the new Māori Party that formed around her. On the same day that Turia announced her resignation, Prime Minister Helen Clark sacked her from her ministerial posts.

Her supporters see Turia as having bravely defied her party in order to stand up for her principles. The Labour Party has criticised Turia for putting the foreshore and seabed issue before the party's wider policies for Māori development, and says that she has unreasonably focused on a single issue. Helen Clark said that Turia had shown "an astonishing lack of perspective". Turia described the Te Tai Hauauru by-election of 10 July 2004 as a chance to test her mandate, and to ensure that she had the support of her voters, but doubts remained about the significance of the by-election, since none of the major parties put forward candidates. Labour called the event "a waste of time and money", although the by-election was required by waka-jumping law in force at the time.[4]

Turia received 92.74% of the vote in the by-election,[5] and resumed her seat in Parliament on 27 July 2004.

Turia and Pita Sharples in 2005

On 17 September 2005, the Māori Party contested the general election with electoral candidates in all seven of the Māori seats. Turia was re-elected in Te Tai Hauauru and that night three more Māori Party candidates won parliamentary seats, Pita Sharples (co-leader) in Tamaki Makaurau, Hone Harawira in Te Tai Tokerau and Te Ururoa Flavell in Waiariki. The winning of the four seats resulted in celebration for their supporters who anticipated seeing an independent, Māori voice in parliament. However, the Māori Party share of the party vote across the country was 2.1 percent, placing them sixth out of the eight parties in parliament by party vote. This was attributed to voters in the Māori electorates mainly giving their party vote to the incumbent Labour government.

Support for the Māori Party in the 2008 general election increased with the party gaining an additional seat.[6] National won most seats overall, to form a minority government with support from the Māori Party as well as ACT New Zealand and United Future. In return for Māori Party support in confidence and supply, John Key agreed to not abolish the Māori seats without the consent of Māori.[7] It was also agreed to review the Foreshore and Seabed Act 2004 and to consider Māori representation in a wider constitutional review which began in 2010.[8] Turia and co-leader Sharples were both made Ministers, although like other support party members both remained outside Cabinet. Turia was given the portfolios of Minister for the Community and Voluntary Sector, Associate Minister of Health and Associate Minister for Social Development and Employment, while Sharples was made Minister of Māori Affairs.[9]

When Paula Bennett stepped down as Minister for Disability Issues on 30 June 2009, Key appointed Turia the new minister.[10] In 2010, the National and Māori Parties announced Whānau Ora, a taskforce designed to streamline social service resources. Turia was announced Minister responsible for the implementing of the scheme.[11]

On 7 April 2011, during the term of the 49th New Zealand Parliament, the composition of the Abortion Supervisory Committee was debated. Turia moved that an anti-abortion Pacific Island doctor, Ate Moala, be appointed to the ASC. The vote was lost 70–30 against, with twenty absences or abstentions.[12]

Turia confirmed in November 2013 that she would retire at the 2014 election.[13]
