Two women have been found guilty of attempting to murder a teenager in the Dome Valley last May.
A jury took five and a half hours at the High Court at Auckland to convict Nicola Jones and Julie-Ann Torrance of egging co-accused Wayne Blackett on as he tried to snap the 19-year-old's neck.
Blackett had admitted to the attempted murder at the start of the trial after the woman was found left for dead by a roadside north of Auckland, having been hit repeatedly in the head with a hammer.
Torrance was also found guilty of sexually violating the young woman as they held her captive in an Auckland basement and beat her with a cricket wicket and bat.
Jones was found not guilty on that charge.
