Keen netballer Simone Neilson lost two close family members within months to smoking-related cancers.
Even so, the 29-year-old mother continued smoking.
Now it's been three months since Neilson had her last cigarette, and she's crediting Auckland University's Wero quit smoking competition and her Gisborne Horouta premier grade netball team.
"I spend so much time with these girls. It's hard to quit on your own. A big part in helping me kick it was them doing the programme too."
The Wero programme, run by the university's Tobacco Control Research Centre, is a nationwide team stop-smoking competition.
