The children of a woman killed in a triple road fatality, which happened near Nelson during a police pursuit, say they are "reeling from this senseless tragedy".
Carmen Marie Yanko, 53, was in a car that was hit by a vehicle being chased on State Highway 6 on Sunday morning.
"We as Carmen's children are heartbroken and reeling from this senseless tragedy," her children said in a statement on Monday.
"She lived to be a mother and was there for us always. Carmen loved and lived fiercely and will be terribly missed by her family and friends."
The two in the car being pursued also died. Police named them as Johnathan Tairakena, 25, and Phillip Jamie Stretch, 33.
All three deceased are understood to be from the Nelson-Tasman area.
The chase began about 5.40am after police tried to stop a vehicle while looking for a wanted person in Richmond.
The vehicle was driven towards SH6, overtaking a truck and moving to the wrong side of the road, where it crashed into Ms Yanko's oncoming car.
The incident has raised questions about police pursuit policy.
