There are serious concerns for the wellbeing of the second boy involved in yesterday's fatal bridge jump in Raglan.

A 16-year-old local boy died after jumping from the estuary foot bridge yesterday.

Another jumper landed on top of him and he was submerged underwater for about ten minutes.

The second jumper is thought to have left the scene shortly afterwards.

Raglan Area School Principal Malcolm Cox says they don't who he is, but they want to make sure he's ok.

"There is a great deal of concern for that person because obviously they will need a great deal of support," he said.

"Police are very anxious to catch up with him."

Cox says his students are being looked after by the whole community.

"At the assembly this morning we were talking to seniors, I had parents there who'd come in to support, I've got teachers on leave who have come in to support, there are lot of adults that have moved in."

Tributes for the teenager began flowing yesterday as news of his death reached the wider community.

A relative told the Herald last night that the whanau including the teenager's parents -- were holding a family meeting and coming together to support each other.

The teen was well-known in the Raglan community and particularly Whaingaroa, where he grew up.

He is a former student of Raglan Area School and was known for his love of sports, including basketball, waka ama and outdoor lawn bowls.

He was also a keen swimmer and knew the waters he eventually lost his life in very well.
