The two teens accused of a brutal machete attack on a police officer are to be charged with attempted murder when they appear in court on Wednesday.
Waiouru Senior Constable Bruce Mellor was attacked with a machete and left for dead after he pulled over a car near Taihape on December 11.
A passing motorist found him lying in a pool of blood.
He was rushed to Palmerston North Hospital with multiple skull fractures, broken teeth, a broken eye socket, broken jaw, cuts to his arms and a badly damaged finger.
An 18-year-old and a 14-year-old appeared in the Whanganui District Court last week charged with assault. Those charges will be withdrawn and replaced by attempted murder when they appear on Wednesday.
