Many of our New Zealand laws have not kept up with technology so laws designed for one thing are clumsily applied to another. One glaring example of this problem is how the law applies to e-cigarettes. E-cigarettes and ordinary cigarettes are legal and tobacco is legal but the e-liquids that contain nicotine and that are needed for e-cigarettes cannot be sold legally. People can buy e-liquids online and import them for personal use but it is still illegal to sell them.
This will surprise many consumers who have purchased them in New Zealand from both physical and online shops. New Zealand remains in legal limbo with a Ministry of Health that is choosing to not prosecute retailers who flout the law and a government who as yet has not changed a law that clearly needs changing. If Tobacco is legal it makes no sense at all that liquid nicotine should be illegal.
