A 3-year-old girl died after she was hit by a car driven by a relative in West Auckland this morning.
Police said emergency services were called to a home in Te Atatu Peninsula just after 7.30am.
She was taken to hospital by ambulance but died after arriving.
"A police investigation is now underway by CIB staff and the Waitemata serious crash unit," a police spokeswoman said in a statement.
The child's family were being supported by police and Victim Support, she said.
