WELLINGTON: New Zealand’s largest multi-national military exercise is to get even bigger, with more countries taking part in it, the New Zealand Defense Force (NZDF) said on Monday. The Southern Katipo exercise held every two years involves naval, land and air services and more than 2,000 personnel from New Zealand and defence partners including Australia, France, the US, Fiji, Papua New Guinea and Tonga. Singapore and Malaysia have been invited to participate in next year’s drill, increasing the number of international participants from nine to 11, Xinhua news agency quoted the NZDF as saying. The exercise, scheduled for late 2017, would again be held around the west and north of the South Island.
