About the role
As a Mine Warfare 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 NZDF 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.
As an MCDO your career will commence with Warfare Officer Training. The skillsets you develop in the first few years of your career, alongside your Warfare Officer Course mates will be developed as you progress. During breaks in your Warfare Officer training, whenever possible, you will conduct dive training and attachments to the Clearance Diving Group (HMNZS MATATAUA) and/or the diving support vessel (HMNZS MANWANUI) to begin to familiarise yourself with the equipment and operations required of an MCDO.
On achieving your Warfare Officer qualification milestones, you will undertake Mine Warfare and Clearance Diving Officer Training as detailed below. Being an MCDO provides you with a specialised and exciting career but also provides you the option of one day becoming a Captain of your own 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 diving support vessel HMNZS MANAWANUI and other RNZN ships.
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.
As an MCDO, you will be in charge of a team and be responsible for their continued training, well being and career progression.
I’ve lead a team to the Solomon Islands to do some EOD work clearing all the explosive remnants of WWII... To go out and get rid of all that danger for them was pretty cool.
Career progression and training
Once trained, you will be skilled in Mine Warfare and Mine Counter Measures, Clearance Diving, Underwater Engineering and the disposal of explosive ordnance and improvised explosive devices. You will be employed in New Zealand and overseas as part of the Navy’s Littoral Warfare Force. This will include land and maritime based deployments with partner nations and organisations such as the United Nations and NATO.
