All combatant countries in the Second World War came to realise just how expensive modern warfare can be. In New Zealand taxes tripled between 1940 and 1945 so the necessary capital could be raised, with the government taxing to the economic limit.

For those with surplus funds, "National Savings Bonds" were introduced. These were loans made to the government for war purposes to be paid back (with some interest) when peace returned. By 1946, over forty million pounds had been invested in the scheme.   ‘Lend to defend the right to be free!’ was the overarching motto of National Savings and was put on posters, cinema slides and savings books.

With 30 million tickets sold in 1939, New Zealand's cinemas was the perfect place to attract attention!  

The mention of the serviceperson's sacrifice as a compelling reason to offer savings harks back to a theme in the First World War. In New Zealand some labour unions urged the government to raise taxes on the wealthy, arguing that if people's lives were being conscripted, so should capital. This was not directly taken up (but was effected indirectly through taxes on luxury items) and the idea was repeated on this slide.

Almost from it's invention the cinema has played a role in war and morale. In the First World War the New Zealand Government even taxed expensive 'dress circle' theatre seats to raise money for the military. However, this slide was less direct, and comes from the Second World War.

It implores cinema goers (from the comfort of civilian life) to subscribe for the latest war bonds drive. By now most New Zealanders knew the war was going well and victory was near- but the slide reminded people of the energy needed for 'the final push'. The slide would have been shown alongside newsreels of New Zealand forces overseas and maybe was in the intermission of a patriotic film.

In fact, in early 1945 there was an undetected German U-Boat off the East Coast- the war was closer than many would have liked to admit. 

Slides like this would have been shown in cinemas across New Zealand.
