A 2001 supplementary order paper, in Keall's name, proposed further amendments, included new provisions to require at least 50% of a licensed premise to be smokefree.

It proposed Parliament prohibit smoking in all indoor workplaces, including bars, casinos, members’ clubs and restaurants.

"[1] The amended bill would require employers to "take all reasonable steps" to ensure workplaces are smokefree, except for dedicated smoking rooms.

[5] In its consideration by the Committee of the whole House through August to November 2003, amendments by Green Party MP Sue Kedgley were agreed that removed proposed instant fines of up to $400 for individual smokers (infringement provisions of $4000 for non-compliant proprietors remained) and additionally banned sales of toys that imitate the act of smoking to children.

Chadwick's main claim was that the bill would save the lives of about 388 New Zealanders a year who would otherwise have died from inhaling second hand smoke.
