The Ruakākā Surf Lifesaving Patrol search and rescue squad is also using two inflatable rescue boats to help with the task of finding the second man.
On Friday afternoon, one of the missing men was found in the water by the police dive squad.
A police spokesman said it was a devastating development for the family of the men, and they are in everyone’s thoughts.
A rāhui has been put in place for at least five days for the area around The Gap.
Police and volunteers from the agencies involved in the search are continuing with their efforts on Friday afternoon.
The two men had recently moved to New Zealand from India, with their wives and children, and they were staying in central Whangārei, said family spokesman Sijoy Alex, head of the Whangārei Malayalee Association.
The families of the men are being supported by the association and the wider community, and they have been overwhelmed by the support, he said.
A swell of up to 2m was running on Wednesday.
Meanwhile, police have asked members of the public to stay away from the search area, after some private jet skis were seen travelling through the area on Thursday.
While police appreciate the wider public’s support, people have been asked to stay away for the safety of the dive squad and to not impede the professional staff and volunteers in their work, a police spokesperson said.
