He said his father had now lost his only surviving brother and is asking for privacy as he comes to term with his loss.
Police were called to a home on Seon Pl, Birkdale at 8.21pm after reports a person had been stabbed.
Acting Detective Inspector Megan Goldie said a man at the home received moderate injuries and was taken to hospital.
The accused man was arrested at the scene.

After a conversation, a welfare check was done at a property on Lingfield St in Glenfield, 5km away, where a man and woman were found dead.
Goldie said there was no ongoing threat to the wider community.
“This is an awful set of events. I know this will leave many in our community unsettled, but what I can say at this early stage of the investigation is that the offender and victims are all known to each other,” she said.
No one else was being sought in relation to the incident.
A Lingfield St neighbour said about six police cars lined the street when he got home from work about 11pm.
He said he would occasionally stop and talk to the people living in the house, and that they were “nice, quiet people”.
“It’s very sad.”
A neighbour of the Seon Pl address told the Herald his mother ran into his room and told him to look outside.
“It was pretty scary. The street was lined with cops and there were about 10 of them with flashlights surrounding the property.
“Meanwhile, a guy was getting arrested out on the street.”
The accused man appeared in the North Shore District Court yesterday and entered no plea.
He is due to appear in the High Court at Auckland next month.
