He prevailed in the second round during a close contest, opposing him to Tauhiti Nena, a Cabinet Minister in the Temaru government.

In 2017, Tuaiva was embroiled in a misappropriation of public funds case and did not run for reelection.

The election was a three-way race between Patrick Howell, supported by Tuaiva and a minister in the Fritch administration, Moetai Brotherson, a left-wing independentist and the step-son of Oscar Temaru, and Vincent Dubois, a former senator and a right-wing autonomist.

In 2022, Brotherson was reelected with a comfortable margin against his main opponent from Tapura, Tuterai Tumahai, a doctor.

Therefore, he resigned as deputy and was replaced by his substitute, Mereana Reid Arbelot.
