I am from Cambridge, New Zealand.
When WWII began in September 1939 the population of the town and surounding farming districts was around 5000 people. By September 1940, 550 young men and women from Cambridge were serving in the Armed Forces. Over the next five years many more hundreds joined up or were involved.
In WWII Cambridge men went away to serve in the New Zealand Army, the Royal New Zealand Air Force, the Royal Air Force, the Royal Australian Air Force, the Royal Navy, the Royal New Zealand Navy, the Royal Navy Fleet Air Arm, and the Merchant Navy.
Cambridge women joned the Women's Auxiliary Army Corps, the Women's Auxiliary Air Force, the Women's Royal Naval Service and the Red Cross Volunteer Aid Detachment. Several Cambridge nurses served in the Army on the front lines in North Africa and Italy. Cambridge also had girls serving in the Tuis in North Africa and Italy.
At home much was going on for the war effort. Cambridge was mainly a dairy farming community then and around seven dairy factories in the district were producing milk products for the war effort. A major effort was going on to build the Karapiro hydro electric dam, which had its own Army and Home Guard units to protect it from enemy action.
The town raised one of the first Home Guard units in NZ and was the first to reach Company stength in the whole nation. It continued to grow into a full battalion which is staggering for a small communtiy with most of its young men away overseas. There were also units of the Women's Volunteer Service, Country Women's Institute, Federated Farmers, Air Force Relations (who knitted woolens for the RNZAF), Emergeny Precautions Scheme and other wartime home front organisations in the town. Many of our girls were Manpowered into both the Woman's Land Army growing beef, lamb, pork and crops for the war effort, and into Munitions at the nearby Hamilton factory. From what I can make out form my research, virtually no-one in the entire community was untouched by the war, every person contributed in some way, even the kids who collected old tins for the Home Guard to make into jam tin bombs, and other war effort scrap.
The only major wartime installation however remained a mystery to most who lived here then, a top secret Air Force fuel storage facility was installed in the park next to the railway station as an emergency reserve should the enemy bomb the airfield supplies. It was in the centre of town and most never knew it was there.
