And it's clear the kaupapa is close to the community's heart with many marae members sharing stories of loved ones who have succumbed to smoking-related illnesses.
"For the future generation and the health of our young people - this is what the kaupapa is all about.
"If you don't have some measures or some level of commitment to our people that we're trying to help them, then we're failing. I'd rather fail trying than not try at all," says committee member Frank Herbert.
Another member Hepa Stephens says the policy has been launched as an expression of aroha with the ultimate goal of retaining the marae as a central place where good health is normal.
"We want to make our marae a place where everyone can learn our tikanga and our reo, and enjoy good health. The marae is the place for that," he said.
There has been some preliminary resistance from some sections of the community and the committee is looking at ways to be sensitive and empathetic to smokers' needs while retaining the integrity of the marae policy.
But for now, it's a cause for celebration says Hauora Hokianga smoking cessation practitioner Pat Dargaville.
"This is a big thing. To have Morehu Marae be the first in Pawarenga to take up the policy is excellent. It sends a great message to whanau and the kaupapa is, do you want to stay around a bit longer for your mokos?" she said.
