Harawira resigned from the Māori Party in early 2011 and became an independent MP. On 11 May 2011, he resigned from Parliament effective 20 May, seeking a mandate for his new party, the Mana Party. This caused the 25 June 2011 by-election, which was contested by five parties, with the main contenders Harawira, Kelvin Davis (Labour Party) and Solomon Tipene (Māori Party). Harawira retained the electorate with a majority of 1,117, his previous majority being over 6,000. In the 2011 general election some months later, Harawira had a similar majority to Davis.
