A teenager has been referred to Youth Aid over the attack on a Kawhia police officer on January 11.
Constable Perry Griffin was knocked to the ground at the Waikato seaside town's wharf by a group who allegedly kicked him and took his Taser, radio and pepper spray.
Inspector Paul Carpenter of Waikato police said a 15-year-old boy had been referred to Youth Aid as a result.
He also said Mr Griffin had been buoyed by the support he had received from colleagues and the public, with 450 messages of encouragement on one police station's Facebook page.
"Such public backing is not just reassuring for the officer directly involved but for Waikato police in general ...''.
