One woman allegedly used a brick as a weapon and tried to shoot the officer with his own Taser after it was taken from him.
When she was unable to fire it, she smashed it.
In court today, police withdrew the sole charge of aggravated assault on police against 19-year-old Kiki Uelese, of Wellington.
Alissa Sailo Gooding, 25, and Joshua Terrence Dennis Pilisi-Mohetaue, 28, both from Dargaville, were remanded without plea for a post committal conference on February 28.
Gooding is charged with injuring with intent to cause grievous bodily harm, assaulting police with a weapon and damage to police property (a Taser), while Pilisi-Mohetaue is charged with injuring with intent to cause grievous bodily harm.
William Campbell-Tahere, 17, had a charge of escaping custody withdrawn, but still faces three other charges.
He entered no plea to two of wilful damage and one of disorderly behaviour.
