Mr Mataki-Kaiaruna said the family was doing okay and the support from the local churches and community had been a big comfort.
"I have never seen a community support a grieving family the way Tokoroa's community has. The way they have banded around us and given us kai and support has been overwhelming and has gone a long way to helping us through this time."
He said around 600 people were expected to turn out to the pair's funeral this Thursday at 11am at the Church of Jesus Christ of Latter-day Saints, Duke St, Tokoroa.
Tokoroa police Senior Sergeant Daniel Peat said the mother and daughter shared a birthday.
National police road policing manager Superintendent Steve Greally said there had been too many crashes since the holiday period began.
"People's driving behaviour has not been safe. Some families have already had their Christmas holiday ruined by these tragedies.
Mr Greally said he wanted to stress that many of these crashes could have been avoided if "people kept their wits about them and had driven with care and caution".
"People need to drive to the conditions. There's a lot of traffic on the roads over this time, and we all need to take more care."
