They had walked back to the marae, from where she subsequently disappeared.
Friends and family became alarmed when Ms Moka had not used her cell phone or bank account for a week.
Her body was not found in an initial search around the marae and crash scene, because it was just outside the search boundary. Police would say only that information from the public eventually led them to her.
The Moka and Korewha families were kept on opposite sides of the courtroom yesterday, but there was no obvious sign of tension. The only interruption came after a discussion on name suppression when a Moka family supporter called out: "Name yourself man, you ******* idiot."
Ms Moka worked as a receptionist at the Copthorne Hotel at Omapere. Her four children, aged 7 to 15, did not live with her. It is understood she was buried in Auckland where most of her whanau now live.
Korewha, who lived on Rawene's Parnell Street, had been employed as a tour guide at Footprints Waipoua and Crossing Hokianga, award-winning ecotourism ventures that offer twilight walks in Waipoua Forest and cruises on the Hokianga Harbour.
The Footprints Waipoua website said Korewha had been studying sustainable rural development at NorthTec. He had previously volunteered with World Vision and Doctors Without Borders in countries such as Malawi, Ethiopia, Cameroon and Algeria. After returning to New Zealand in 2009 he initially worked for Ngapuhi Iwi Social Services.
