"The whānau say 'wow, that's awesome - I never thought you'd give up. If you can, I'm going to try'."
Tapa said three of his immediate whānau had now been smoke-free for more than three months and had "no desire" to return to smoking.
"Other whānau members are now seriously looking at their smoking habits and are starting the journey to being smoke-free."
Getting active or keeping active before giving up would help with the smoke-free journey, Tapa said.
"The key message is that your mind has to be ready for the change.
"Get that ready and the journey is a lot easier.
"As we say, the top two inches will decide your pathway."
