"It's a real tough injury to deal with," Iro explained. "At the end of the day it's just a game of rugby league ... I'm very proud of the people involved.
"Education is the most important thing, it just needs to be continued. One of the benefits a high profile injury has [such as McKinnon's in the NRL] is the impact it has on those who are watching and recognising the seriousness of an injury.
"With the media that has been around the recent injury it has highlighted [the proper process]."
Rugby League Northland general manager Alex Smits also commended Smith and the others who were involved, saying they could easily have been dealing with a newly diagnosed quadriplegic.
"Rugby league can be a dangerous sport and accidents can happen, but if we all have an action plan on how to manage these situations, then a lot of harm can be avoided and the golden rule is - never move an injured player," Smits said.
