A five-year old boy who died north-west of Auckland this afternoon drowned after his quad bike crashed into a creek, police have confirmed.
Emergency services including a rescue helicopter were called to a lifestyle block in Kumeu just before 3.30pm but the boy could not be saved.
The cause of the crash was being investigated by the serious crash unit.
Police said a post mortem would be carried out to determine the cause of the boy's death but St John's earlier confirmed he had drowned.
AWRH spokeswoman Kerrie Spicer said a paramedic and doctor on board worked for about 45 minutes on the boy before he was pronounced dead at the scene.
