A first aid kit should be appropriate for the types of injuries and illnesses likely to occur at the workplace.

Each employer must provide at least one full basic first aid kit in each place of work, including company vehicles. (Regulations 4 and 7 of the Health and Safety in Employment Regulations 1995). Where there are more than 50 employees, an additional kit should be provided and for every 50 employees thereafter, another additional kit.(Department of Labour NZ)
