The New Zealand Defence force is leading this year's ANZAC dawn service at Gallipoli in Turkey. It's also leading Aotearoa's service at Chunuk Bair; the hill captured by Kiwi soldiers but later lost to an Ottoman counter attack, after the New Zealand soldiers had been relieved. More than 16,000 New Zealanders served in the campaign and almost 2,700 of them died; about a sixth of all those who had landed on the peninsula. A campaign that's played a signficant role in New Zealand national identity. John Mcleod spoke to Lisa Owen.
