Wellington police are searching for missing teacher Isaac Levings who was last seen on the capital's waterfront on Wednesday night.
It's been two days since Levings was last seen at about 10:30pm on Wednesday after the 1975 concert.
Police told Newshub staff are conducting water-based- searches, but are not ruling out other possible search areas.
Levings was wearing a grey t-shirt, black shorts and white shoes.
"Police and Isaac's family have concerns for his welfare."
Pictures captured by Newshub show a police boat in Wellington's harbour with dive staff onboard.
Wellington police are urging anyone who has information on Levings' whereabouts to call police on 105 and quote file number 230420/8092.
