Police divers and other emergency service agencies have finished today's Murrumbidgee River search for the 23-year-old who hasn't been seen for close to 24 hours.

The search will resume tomorrow with a boat to patrol each side of the river at 7am. 

Divers will then take to the water at about 8am.

4pm: EMERGENCY crews have finished scouring the banks of the Murrumbidgee River in Wagga as the search for a missing 23-year-old man continues in the water.

Inspector Peter Robertson, from Wagga police, said volunteers from the State Emergency Service (SES) and members of the Volunteer Rescue Association (VRA) had completed their land search. 

Police trail bikes were also used.

Members of the man's family - including two people believed to be his parents - have watched on as police divers continue to conduct sweeps of the water.

The level of the river means they are yet to don their full diving gear. 

"They'll keep doing the sweeps they've been doing because the river's so shallow," Inspector Robertson told The Daily Advertiser on Saturday afternoon.

The search will continue until it gets dark.

Inspector Robertson confirmed a short time ago that it would resume tomorrow, if nothing is found prior.

"The divers will be back in the morning to finish their search," he said.

A boat is expected to patrol each side of the river at 7am, with divers due to begin their search at about 8am.

It is anticipated they will conduct underwater searches on Sunday.

2pm: POLICE are investigating "all possibilities" into the disappearance of a Wagga man.

A land and water search is under way for the 23-year-old who went missing on Friday night.

The man was last seen around the Murrumbidgee River just downstream of the boat ramp at Wiradjuri Reserve shortly before 8.30pm.

Inspector Peter Robertson from Wagga police said the man was with a female who alerted police.

The call sparked a two-hour land and water search with the help of Volunteer Rescue Association (VRA) members which was called off at 10.30pm on Friday.

On Saturday they have been joined by at least a dozen State Emergency Service (SES) volunteers and Sydney-based police divers, who arrived shortly after 12.30pm on Saturday.

Inspector Robertson said the search started again at 8am using police trail bikes, the SES and VRA.

It will concentrate on a section of river spanning about 500 metres downstream of the boat ramp.

A mobile command post has been established.

"In conjunction with that the police divers have just arrived from Sydney and they'll shortly set up and start searching the river as well," Inspector Robertson said.

"We don't have a 100 per cent guarantee that he is in the river but our other inquiries in town this morning, at locations we believe he has either been staying at or being frequenting lately, have turned up negative."

"We've spoken to other members of his family, other acquaintances and friends of his, and no one has seen him since yesterday afternoon."

Inspector Robertson told The Daily Advertiser that officers had received little information from the female, meaning the exact circumstances surrounding his disappearance are unclear.

"We are investigating all possibilities, at the moment it is a possibility that he is in the river," Inspector Robertson said.

"He is quite a tall man though and the river is quite shallow and not fast flowing.

"It is possible he has come out of the river last night after the girl couldn't find him ... or at any stage during the night.

"We haven't been able to locate any sign of him."

1pm: Police divers have arrived in Wagga to join a land and river search for a 23-year-old man.

The man was last seen on the banks of the Murrumbidgee River at Wiradjuri Reserve, near the CBD, some time on Friday night.

Volunteers from the State Emergency Service and Volunteer Rescue Association have been on the water all morning, but are yet to find any sign of the missing man.

A mobile command centre has been established at Wiradjuri Reserve.
