A man assaulted by partygoers in Lower Hutt early on Sunday morning is unlikely to survive, say police.
He was found with serious head injuries on Seddon St in Naenae at 3:27am and is currently in Hutt Hospital's intensive care unit.
Police say the man was chased by a group of people who were at a 21st party on Cleland Cres. The party was attended by more than 30 people, and police are appealing for witnesses to come forward.
A 27-year-old man has been arrested and charged with assault, and further charges may be laid. He will appear in the Lower Hutt District Court on Monday.
Anyone with any information is urged to contact police on (04) 560 2600 or Crimestoppers anonymously on 0800 555 111.
