New Zealand would be the second country in the world to approve plain packets, after Australia. The United Kingdom and Ireland were also considering a law change.
Australia was facing dual legal challenges from tobacco companies and tobacco-producing countries after introducing olive-green, standardised packs in December.
New Zealand was also likely to face legal challenges if it followed Australia's lead, and officials have estimated the cost of a legal dispute as between $2 million to $6 million, not including compensation if a case was lost.
Mrs Turia said New Zealand was keeping a close eye on the World Trade Organisation (WTO) challenges against Australia by tobacco-producing countries Ukraine, Honduras, Dominican Republic, Cuba and Indonesia.
She was confident that a plain packaging regime would be in line with New Zealand's WTO obligations: "That is why we are pushing forward to take the legislation through the Parliamentary processes without delay."
Some have expressed concern that the New Zealand's inclusion in the Trans-Pacific Partnership (TPP) would give companies a direct pathway to sue Government, but the legislation was likely to be passed before the TPP was signed off.
