The incident happened in Onehunga, about 10pm, on Inkerman St.
A photographer at the scene said he arrived at the scene about 10.20pm to find several police officers on the street.
"When I arrived, an ambulance was on the scene with multiple police cars.
"There were a couple of wheelie bins in the middle of the road. They looked like they had been hit [by a car],'' he said.
Rubbish littered part of the road and it appeared the incident had occurred on the opposite side of those bins, the photographer said.
"There were a few people who were talking to police too.''
Neighbours were being interviewed by officers.
St John said they were called to an incident on the street about 10.14pm.
"We sent one ambulance and one rapid response unit.
"We treated and transported one patient in a moderate condition to Middlemore Hospital emergency department.''
Police said the victim's car was stolen and the woman he was due to meet also left with the two men.
Authorities said the pair had already met in person and last night's rendezvous would have been their second meeting.
Police are now making inquiries into the incident.
