Northland MP Mike Sabin, representatives from the Northland Rugby Union, including Jeremy Parkinson, Andrew Golightly, Greg Shipton, and Ajit Balasingham, and former NRU chair Wayne Peters were among those present.
Otamatea Hawks player Zane Phillips participated in the emotionally-charged haka which he reckoned befitted the high regard Jordan's teammates held him in.
"It (haka) shows how much mana he had. That was our powhiri. He's our bro," Mr Phillips said.
He said Jordan was an "awesome dude" who he had known since childhood.
Danny Morgan of Kaiwaka was also at the funeral and described Jordan as an "up and coming" rugby player. He and Jordan's father Aaron are first cousins.
Mr Morgan and his daughter used to run a kapa haka group for Otamatea High School which Jordan and his sisters were members of.
"He was very quiet but got down and did his job. Very polite boy ... it's a big loss," said the quarry worker.
Mr Morgan said he was present at the Otamatea Hawks vs Wellsford match in Kaiwaka early this year when Jordan received his first head knock.
He said Jordan got up after the knock and walked a few metres before he was seen by St John ambulance paramedics.
Jordan, 17, died from suspected brain bleed on Sunday suffered during a match between his Otamatea Hawks premier reserves and Old Boys Marist at Kensington Park the previous day.
