"[On Saturday afternoon] there was a young, fit 17-year-old playing rugby and today he is not with us. That's hugely tragic." Wairarapa Bush chief executive Tony Hargood said he found the news of Jordan's death "gut wrenching".
He said the union had offered their condolences to Jordan's family and had been in touch with Mr Parkinson to offer support.
The union's stance was to do "all they can" to prevent head knocks happening in the first place, mainly through coaching proper technique so there was less chance of serious head clashes, he said.
"There are 169 coaches in Wairarapa. They must all take a Rugby Smart course, which teaches them to take concussion extremely seriously."
The course is a one-hour session with ACC, teaching injury prevention and concussion management. Coaches are not registered on the database until they have completed the course.
The official stance after a player has suffered a concussion is that "a player cannot return to training until three weeks after the incident or after medical clearance."
"We recognise that it is a contact sport. Our coaching is world class. We have the right equipment, and our coaches are educated and know how to manage players," Mr Hargood said.
He said the science behind concussion was that the brain "jars" inside the skull and head gear had been proven to be ineffective in preventing that.
Introducing compulsory head gear was not a likely measure the union would take but he said he did not discourage the use of head gear.
"It's about coaching correct technique," Mr Hargood said.
"A mouthguard is also very important, because it can reduce jarring."
Northland Rugby Union has been trialling a "blue card" system, whereby a player can be sent off immediately if a concussion is suspected.
Mr Hargood said that system was something the union was "seriously considering".
"Going forward, we will look at introducing the blue card. We monitor the team sheet closely [to make sure coaches are keeping to the concussion rules]."
"The union will always help support players and coaches".
The NZ Herald reported concussion expert Dr Rosamund Hill as saying there was a growing awareness around the risks associated with concussions.
"It does make people aware that there are risks in playing contact sport, and particularly rugby.
"In the past, it has been sort of ignored a bit and overlooked a bit, so I think there is definitely a growing awareness that it is a serious problem and it needs to be looked at very carefully."
