At the centre of the paving on each side is buried soil from Gallipoli, the birth of the ANZAC tradition as soldiers fought together in the Australian and New Zealand Army Corps in 1915. A ceremony held on 26 February 2001 soil from Chunuk Bair was buried in a rimu box on the New Zealand side, while on the Australian side, soil from Lone Pine was buried in a box made from Australian jarrah.
