Otamatea Hawks team manager Karyn Hodgson said they were also waiting for news.
Teammates gave the boys a stirring haka as they were taken onto the rescue helicopter, Hodgson said.
"The boys all lined up as they were carried through on stretchers, and did a haka for them. It was amazing."
One boy received a neck injury in a ruck, the other was unintentionally struck in the head in a separate incident, she said.
Another Otamatea coach, Dean Kenny, was at the ground and said the boy with a neck injury was "drifting in and out of consciousness".
He understood the second boy was hurt when he was struck in the head by a boot soon after.
The game, which was being played against Wellsford, was called off half an hour into the first half, Kenny said.
A Hawks player coached by Kenny, 17-year-old Jordan Kemp, died in July last year after suffering a head injury during a game.
