Tukituki MP and Veterans Affairs Minister Craig Foss escorted Prince Charles and Prince Harry, at Gallipoli events on Anzac Day in Gallipoli.
"Taking Prince Harry to meet some Kiwis in the New Zealand crowd at Chunuk Bair was a great privilege and fun," Mr Foss said.
Mr Foss attended ceremonies for the many nations involved in the unsuccessful eight-month campaign, starting with a dawn service at Anzac Cove.
He Tweeted he enjoyed sitting beside former New Zealand Prime Minister Helen Clark, now Administrator of the United Nations Development Programme.
He did not know he had a family connection with World War I until his ministerial appointment piqued his interest last year. To his and his family's surprise, two great-grandparents fought on the Western Front with the British army. Mr Foss proudly wore replicas of their medals.
