Jacob Lawgun will be heading over as the assistant coach for weightlifting, while James Morris will be an official for table tennis.
Sport Northland chief executive Brent Eastwood said it's great to see so many Northlanders heading to Rio.
"It goes to show what we have always thought. Northland probably punches above its weight when it comes to national sporting selections, given our population and low socio-economic status," he said.
"We are certainly a feeder province, but we know know the talent exists here in Northland, the issue for Northland is always to identify and develop that talent with the resources we have."
Having the number of Olympic and Paralympic athletes that Northland has, provides a great incentive for those coming through the ranks.
"Having so many Northland Olympians is fantastic in terms of role-modelling for our youngsters," Eastwood said. "Our youth look up to these athletes and are inspired to think that they can go on to represent NZ on the world stage having grown up in Northland."
Kerikeri's Blair Tuke shapes as Northland's greatest hope for Olympic gold, although the sevens sides and the women's hockey team will be in the medal hunt.
Paralympic swimmer Cameron Leslie is a hot favourite for gold in the pool at Rio.
