A 5-year-old boy has died in a driveway incident in Pokeno this afternoon, police say.
Police arrived at the scene at about 4pm. The boy was unable to be revived and passed away at the scene.
It was understood the boy and a sibling were riding on the trailer, carrying a small digger, which was being towed by a 4X4 vehicle.
The serious crash unit and police photographer are at the scene and the incident will be investigated.
"This is an incredibly tragic scene for everyone involved,'' says Inspector Neil Fisher, Counties Manukau road policing manager.
