Trentham Gymnasium

Trentham Gymnasium stands as the original location for the first NZ Army Physical Training Corps parade on the 24th November, 1988. The gymnasium now caters for all ages and enthusiasm levels.

Physical Training Instructors (PTI) work from the Trentham Gymnasium. They have an array of skills to help individuals and collective groups with their physical health and wellbeing in various environments.

They are:

Group Fitness Classes 

A variety of classes throughout the week ranging from formal training to lunchtime circuits. Classes vary from week-to-week and formal training takes priority of facilities. For more information about bookings, contact the Gym Staff.

Individual Training Programmes

Individualised programmes can be provided with a PTI to help you achieve your specific training goals; whether you want to improve your general fitness, a specific training component such as strength or endurance, or have a targeted event in mind.

Exercise Rehabilitation 

If you're injured, the Exercise Rehabilitation Instructor will work with you in conjunction with the Physiotherapist to ensure you can get back to training as quickly as possible. Personnel will be given time and support to rehabilitate their injury back to full fitness, as well as maintaining overall fitness where possible.   

Recreational Training and Sports 

A variety of sports tournaments are conducted throughout the year, as well as periodic recreational events.

Strength and Conditioning

The Gymnasium provides the equipment and resources to train for your specific goals. PTIs can provide guidance on training advice and technique when needed.

Injury Management and Prevention 

At times, you may have an injury due to the nature of sports or military training. PTIs can provide advice around injury prevention or concerns you may have, or direct you to the Physiotherapist for treatment and management.



Trentham Camp has two large training facilities for personnel. The main gymnasium is the size of a basketball court, and this facility also has a weights room attached to the end. The weights room has a variety of equipment ranging from lifting platforms, to cardio equipment, machine and free weights, as well as other equipment to help support individuals with their training.
