Police and ambulance were called to an address in Marjorie Jayne Cres, Otahuhu around 1:10am today to reports one person had been critically injured.
Inquiries suggest two men, who were known to each other, had got into an altercation at a private residence.
The man who was initially in a critical condition is now understood to be in a serious condition in hospital.
A 50 year old Otahuhu man is expected to appear in Manukau District Court today on serious charges, which are yet to be confirmed.
