Rasmussen said such events were always a "great opportunity" to put the knowledge gained and skills learned to use in a challenging environment, and the bonus was working in with soldiers from New Zealand's ally and partner nations.
The three-week exercise runs until October 19 and involves Royal New Zealand Navy, New Zealand Army, and Royal New Zealand Air Force units along with supporting units.
An army spokesperson said the reservists regularly worked and trained in with their regular force counterparts and that training provided great benefits to their civilian roles, benefiting employers and communities.
