To work as a diver, you must:
- be at least 18 years old
- have a current medical clearance from the Diving Hyperbaric Medicine Service
- have a Certificate of Competence, issued by the Occupational Safety and Health Service of the Ministry of Business, Innovation and Employment. This must be renewed every 5 years.
Most commercial divers also complete more advanced or specalised dive tickets, up to the level of dive master. Police, navy and customs divers must first enlist with their respective forces. Divers may also need licences for operating heavy machinery, vehicles or boats.
