A woman and a young girl remain in critical condition following a serious crash near Okere Falls.
A Waikato Hospital media spokeswoman said the woman was still in the intensive care unit and the girl had been transferred with critical head injuries to Starship Hospital in Auckland.
The girl isbelieved to be aged around 4-6, though her exact age is unclear.
Two other children, both under 1, were also transferred to Starship Hospital from Rotorua Hospital last night.
They were among the seven people injured in the crash, which happened around 3pm on State Highway 33 yesterday.
"It will take a while to determine the factors that led to the crash and the Serious Crash Unit is assessing those factors. It is way too early to contemplate charges."
