"The reality is that unless we do something about it now, within a couple of generations of humans [kiwis] could be completely extinct."
She said having the New Zealand league team involved was beneficial in raising awareness.
"It really helps when prestigious people get involved ... but it is also about getting all New Zealanders involved."
The players were given an "eye-opening" briefing on the current statistics for the endangered species, and the link between the league team and the flightless bird hit home with some players.
"If we didn't have the kiwi bird, what would our team be called?" said Blair.
Kiwis hooker Issac Luke said the link between the bird and the team was important.
"It's awesome to have a great meaning behind it ... not only for our jerseys but for our country too," he said.
Kiwis for Kiwi Trust, which has been running for 12 years, has made some improvements for the kiwi population.
"There was a 4 per cent losing rate of kiwis per year during the 1990s, and we are now at 2 per cent per year ... so there has been progress," Ms Impey said.
The New Zealand Kiwis will travel to Whangarei this weekend to take on Toa Samoa in the Four Nations competition on Saturday.
