Members of a family injured in a crash which killed a young girl on Friday remain in hospital.

Five people were taken to hospital following a two-car collision on State Highway 1, near St Andrews south of Timaru.

It is believed the child and her family were from Auckland, and had been holidaying in the South Island.

Two people were critically injured in the crash, while three others were also injured.

Three people remain in hospital, but the family have requested no condition updates be released to media.

However, it is understood that two members of the family are still in a critical condition and a third serious.

Two people from the second car were earlier discharged from Timaru Hospital.
