New Zealand Post is celebrating the Queen’s 90th birthday with a special series of stamps and a limited edition silver coin.

It's produced ‘lenticular’ or moving stamps that feature nine different images of the Queen on just three stamps.

Spokesman Simon Allison says simply tilt the stamps to watch the images change, from the Queen’s christening in 1926 right through to her attending Anzac Day Centenary commemorations in London last year.

As well as the stamps, New Zealand Post is issuing a 1oz silver coin featuring the Queen at her christening.
