The half-brother of Labour MP Kiri Allan has admitted he killed his partner in Whanganui.
On Thursday, Eric Ara Mete, 51, pleaded guilty to murdering his partner Lorna-Anne Marie Thompson in April 2019.
Thompson was dead for at least five days before being found. She was a mother of five children.
In 2019 Allan told Newshub she was devastated by her family link to the tragedy.
"It's been an extremely trying time for our whānau and our thoughts and all our aroha have been with the victim and her whānau at this time."
Allan comes from a family of 10 and grew up in a separate community and town from her older brother but says she still feels connected.
"His children are still my nieces and my nephews and at the end of the day we're still whānau," she told media.
Newshub understands Mete has struggled with methamphetamine use with Allan saying the drug had a "devastating impact" on her family and community.
Mete will be sentenced on 8 May.
