That was followed by a waiata, after which faint strains of bagpipes and bugle calls could be heard across the cemetery from other nations' services.
"I say to you gentlemen, I salute you, I salute your bravery and your courage," said Prime Minister John Key.
"This service is all the more special and powerful for your presence."
Mateship remembered
At 88, John Bridgewater, of Mt Albert, is the oldest member of the 30-strong veterans group visiting South Korea this week.
Yesterday, at the UN War Cemetery in southern city Busan, he placed a poppy on the grave of his friend Ray Carson, who died in 1953 at 22.
Mr Carson was killed when a "Quad" truck used to tow field guns overturned in treacherous battlefield conditions.
After the services and a gruelling week of travel and visits to former battlefields to the north, Mr Bridgewater was tired but pleased to see Mr Carson's grave, where he spent several minutes.
"We went about together, he was a bit younger than me.
"He had a girlfriend in Christchurch, and he'd send her stuff. I'd help him pick it out."
