Child Resistant Closures

Child resistant closures help to significantly reduce the chances of a child accessing a drug or chemical. They are legally required on some medication and chemicals, and can be purchased from pharmacies for use on other products

Child resistant closures are not "child proof" They are designed to increase the time it takes for a younger child to access the medication or chemical.
They are "packaging that is designed or constructed to be significantly difficult for most children under five years of age to open or obtain a toxic amount of the substance within a reasonable time. It is not child proof packaging."

Types of Child Resistant Closure

Child resistant closures include both re-closeable and non re-closeable packaging.

Non re-closeable closures are packages like aluminium foil (strip packaging) or opaque/clear laminated plastic (blister packaging) generally contain a single tablet (such as a medicine or dishwasher tablet,)

Re-closeable packaging involves a container fitted with a re-closeable top, or a child safety cap such as the "Palm-n-Turn" or "Clic-Loc" variety (such as methylated spirits or dishwasher powders).

In New Zealand, child safety caps are required to meet the current New Zealand Standard (NZS 5825:1991). The majority of caps are mainly of the "palm-n-turn" variety. Recently on the market, there are the "3rd generation caps" available which allow an increased level of protection whilst providing easier access for adults.

General Prevention Advice

  • Child resistant closures need to be used correctly to be able to limit the chances of a poisoning. Turn it until you hear a click, and make sure you can't just pull it off


  • Always replace the child resistant closure correctly after each and every use. Never leave a lid off to make it easier to use the product; this also makes it easier for a child to be poisoned


  • Products with child resistant closures still need to be stored in a secure location.
