Police have named the man killed outside the Christchurch City Mission as Jordan Morris.
Officers were called to it's men's emergency night shelter on Hereford Street just after 10pm 10 March after reports of a man being stabbed.
Detective Senior Sergeant Craig Johnson said Morris, a Christchurch resident, died a short time later.
Another man, 67, has been charged with his murder and is due to reappear in Christchurch High Court on 12 April.
Christchurch City Missioner Corinne Haines has previously said it was "tragic" that such an event would happen on the organisation's premises.
"We offer our thoughts and prayers to the families of those affected and deeply appreciate the efforts of our amazing staff along with emergency services last night," she said.
