A man has died in hospital four days after he was beaten outside Wellington's Te Papa.
The victim had his life support switched off on Wednesday.
A 28-year-old man had previously been charged with wounding with intent to injure in relation to the beating and police say they are not looking for anyone else in connection with what is now a homicide.
However they say a decision around further charges is yet to be made.
Police are still talking to witnesses, and are interested in speaking to anyone who either saw the assault, or was in the Te Papa car park area on Saturday between 7 and 7:20pm.
Anyone with information is asked to contact police on 105.
