Vaping products could not exceed 20mg/mL for freebase nicotine or 50mg/mL for nicotine salt products. It wasn't possible to notify products through HARP that exceeded those limits.
Manufacturers or importers of vaping products could face a $400,000 fine for breaching nicotine level regulations.
The director general of health was also able to order a recall of products if they posed an unacceptable health risk.
The Ministry of Health was looking at a number of steps to enhance the monitoring of compliance with regulations, including requiring manufacturers and importers to review their notifications to HARP.
"If any notifiers that find that their products exceed the nicotine salt limit, we will instruct them to withdraw their product notification and cease selling those products immediately, including communicating these actions to any distributors and retailers that may be stocking their products."
