Christchurch's Air Force Museum of New Zealand is about to celebrate 100 years since the birth of New Zealand military aviation at Wigram itself.

The Royal New Zealand Air Force as we know it today dates back to 1937, but the full history of military aviation in New Zealand goes back further than that.

Museum Research Curator Simon Moody says it all began just before the First World War when local businessman and former Mayor of Christchurch Sir Henry Wigram visited Europe and witnessed the huge strides taking place in aviation.

Keenly aware of the potential of both military and civilian aviation, in 1915 Sir Henry, also a long-serving member of the Legislative Council, opened the Canterbury Aviation Company, New Zealand's second flying school, on land he bought at Sockburn.

'Sir Henry was one of the individuals instrumental in promoting New Zealand's understanding of the part air power would play in future combat.”

The New Zealand Permanent Air Force was established on June 14, 1923, and a week later the New Zealand Government purchased a large portion of Sockburn Airfield from Sir Henry Wigram, at a much subsidised price, which would subsequently be renamed Wigram in his honour.

Wigram is now the site of the Air Force Museum and a centenary exhibition entitled NZPAF100: The Origins of New Zealand Air Power will open to the public on 9 June at the museum.

It will tell the story of how New Zealand went from no standing air force, to the formation of the NZPAF, then on to the foundation of the RNZAF as it is today.

Air Force Museum Research Curator Simon Moody looks through a scrapbook of images compiled by Wing Commander Ralph Cochrane during his service stay in New Zealand from 1936-1939. He was the first Chief of Air Staff for the RNZAF.

Simon has extensively researched the formation of NZPAF and says it's a complicated tale with lots of twists and turns, victories and setbacks.

'This exhibition is about the story of how, 100 years ago, the first steps towards the RNZAF we know today were taken. It looks at what caused the NZPAF to be formed in 1923 at Wigram as part of the Army, and how military aviation developed over the next 15 years.

'While the anniversary of the creation of an independent Air Force - the RNZAF in 1937 - remains our official birthday, this centenary is the basis of that milestone 86 years ago. It marks the founding of our first air base, at Wigram, where the museum stands today.”

The exhibition will acknowledge the experience of around 800 New Zealanders who served in the air or as ground staff for Britain and Australia in the First World War.

It shows that some of those individuals were integral to the development of military aviation in New Zealand during the 1920s and ‘30s.

Simon says this part of history for the RNZAF was important as it helps in understanding how the RNZAF became a separate service.

'The contributions of the pioneering aviators who preceded and then often led it in the early years help us appreciate the context in which military aviation developed in New Zealand between the World Wars.

'It also bridges the gap between those few New Zealanders who served in the British military air services in the First World War and the creation of the citizen RNZAF in time for the Second World War.”

The NZPAF100: The Origins of Military Air Power exhibition will run for six months.

The Museum will celebrate the centenary with a public Gala Day on June 17 at the Air Force Museum.
