A 20-year-old man has been accused of stabbing another man multiple times with two 30cm-long knives at a Porirua property.
Police said a 21-year-old man suffered injuries to his head, neck, arms and leg when he attacked several times with the knives at a house on Azimuth Place in Whitby about 6.30am on Sunday.
Detective Shane Carter said officers arrived on the scene quickly and prevented the attacker inflicting further injuries.
They pointed a Taser at the accused man, but did not deploy it, Mr Carter said.
"The outcome could have been a lot worse had police not attended when they did."
