The couple found dead in their room with a patio gas heater on will be buried alongside a cousin of a similar age tomorrow.
David and Bernadette Otimi, 43 and 41, will be laid to rest alongside the man, who died recently after a long illness, at the burial ground next to Kauriki Marae in Taumarunui.
Police say the pair appear to have died from carbon monoxide poisoning from the heater but are awaiting the results of a toxicology report.
The three Otimi children - all aged under 13 - found their parents' bodies inside their Taupo Rd home about 8.45am last Thursday.
The tamariki are being cared for by whanau at the marae and kept off school for a few days.
