"They went to their first Anzac Day when they were just 4 months old, and this will be their second," Second Lieutenant Thomas, of the Southern Health Support Squadron, said.

At the other end of the age spectrum, Montecillo Veterans Home and Hospital yesterday marked the centenary of Anzac Day services at the South Dunedin rest-home.
Opened in 1918 it held its first Anzac service on April 25, 1919, and planned on holding many more, trust chairman David More said.
"We still have around half a dozen World War 2 veterans here - the oldest is 100 years and six months - but we have residents from other conflicts.
"Montecillo will continue - we will remain as long as our residents want us."
