"They need to start incorporating league into some programmes at schools. I definitely think it is an avenue that should be looked into," Thompson said.
"The Kiwis have just gone to number one in the world and for only Auckland to be a league-driven city, it just shows you how much talent there would be anywhere else if they were playing league."
Thompson says the family atmosphere at the Warriors is different from the other two NRL clubs he was with.
"Over the years the Warriors have gathered that family is a big thing when it comes to the culture of New Zealand people," he said.
"The way they incorporate your family with everything, like presenting the jerseys before the game and inviting the family up for a feed after the game.
"If our families are happy, then we are normally happy."
Thompson does not agree with critics that the Warriors have been their usual inconsistent selves this season.
"I wouldn't say this is a typical start to a Warriors season. It has been quite the opposite.
"The games that we have lost we haven't lost by much and they have been within reach, whereas you normally see big blow-outs at the Warriors.
"This year that has not happened where the score absolutely gets away from us.
"We have been working hard on that and the last three games we have won right at the line, which over the years you have not seen that. It is going well at the moment but we just have to focus on our defence."
The one goal Thompson has not achieved yet is to play test footy for the Kiwis.
He got a taste of it last year after being called into the Kiwis' squad in the Four Nations series but did not get to play.
"It is always a goal of mine at the back of my mind to put on that black jersey. There is no greater honour to represent your country and your family and all that."
