A major police operation is underway to find fugitive Marokopa father Tom Phillips' remaining two children - after he was shot dead by police on a rural Waikato road.

Newstalk ZB reporter Jordan Dunn is near the police operation in the Waikato.

He says a lot of resources have been deployed.

"There are cordons on the way to Marokopa and there's a police presence around where that robbery was. So there's a lot of police that are being put out, a lot of police resources to try and track down these kids."
