Not only has Mrs Dunckley (nee Clarke), a retired music teacher, performed at the Waikouaiti Anzac Day morning services for four decades, but last year she also helped out by playing at an earlier Anzac service at Palmerston before driving south in her Nissan Sentra car to Waikouaiti.
"It's only 15 minutes by car" was her unflappable response to a question about whether there had been any pressure in moving on to a second service which started only half an hour or so after the end of the first.
Mrs Dunckley, who taught music and singing at Waikouaiti for many years, retired and moved to Palmerston in 1992, but faithfully maintains the Waikouaiti link.
And at 87 she is still going strong.
"I'm pretty lucky. I can still do my housework and can still manage most things.
"I do what I can and pay someone to do what I can't."
Asked about the secret to her marathon performance success, she says staying mentally and physically active and having many interests and commitments had definitely helped.
As well as her interest in music, she is also an active and well qualified photographer and, with three children and three grandchildren, family matters have also kept her busy.
As a former Women's Army Auxiliary Corps member during World War 2, she is well aware of the significance of Anzac Day.
She has been married twice, initially to Jim Lean, and subsequently to Jim Dunckley, after her first husband died in 1989.
Mr Dunckley died as a result of a car crash in October 2009.
Both her husbands served overseas in the New Zealand armed forces during World War 2 and she remains grateful they had both returned safely from the war.
After decades of musical dedication, Mrs Dunckley still knows never to say never.
As years have gone by, the physical challenges of performing have increased, but if she was needed in an emergency, she would still step in if needed in the future.
"As long as I was able, I would never see anyone stuck."
But she is quietly hoping this will be her last Anzac Day performance.
