About the role

As a Mine Clearance Diving Officer (MCDO), you will work both above and under the water. You will lead a team of divers in the water doing explosive ordnance disposal, maritime security and mine clearance tasks. You will also manage the overall diving function including safety management, working ashore in a headquarters providing advice about diving capabilities, and commanding a dive team. As an MCDO, you will initially be in charge of a team of up to 10 personnel, and you will be responsible for their continued training, well being, career progression, and the maintenance of dive equipment.

As your career progresses, you will move into command positions, commanding combined detachments of up to 50 personnel overseas on operations and exercises. MCDOs are the Navy's experts in clearance diving, mine counter measures, under water engineering, explosive ordnance disposal and improvised explosive device disposal.

An MCDO is a specialisation of the Warfare Officer role. You will gain the knowledge and opportunities that come with the Warfare Officer role and can also become part of the command team for the RNZN’s Diving Support Vessel or the soon to be commissioned Littoral Operations Ship.

The role of an MCDO is demanding physically and mentally. An MCDO needs to be fit and be able to work in extremely testing conditions. Once you are qualified as an MCDO you can expect various postings: to the Clearance Diving Group, Explosive Ordnance Disposal Squadron, operational deployments to Coalition-led missions, and at sea on the RNZN's Diving Support Vessel as you progress through your career

Job on base

While on base, you will be posted to the Clearance Diving Group as a Team Leader. You will have an important part to play in the planning of future operations and exercises. Your experience and professional ability will be tested as many other Defence Force organisations will come to you for diving assistance and expert advice. Likewise, you will need to assist your team who have equipment issues or organisational matters to resolve. In addition, you can expect to carry out weekly diving to maintain underwater skills, conduct morning physical training as a unit and complete reports, planning and projects.
