Cigarettes packets will be adorned in graphic health warnings by early next year, but the Maori Party wants the Government to lead by example and ban all smoking inside Parliament grounds.
Maori Party co-leader Marama Fox issued the challenge during a speech in support of the legislative changes, which the Maori Party has spent years calling for.
Earlier on Tuesday, the Government used World No Tobacco Day to unveil plans to strip cigarettes of all marketing.
Instead, they will be emblazoned with graphic health warnings depicting the consequences of smoking on human organs.
Lung cancer was the biggest cause of death in New Zealand, with about 5000 Kiwis killed each year from smoking-related diseases.
