"I really don't know why but I just become fascinated by the memorials themselves and the chance to help preserve this very significant part of our history. Many were constructed locally with a great amount of love."
He is team leader at Auckland Libraries' South Auckland Research Centre and said he has a special interest in memorial churches - prominent examples include St David's in Khyber Pass and St Andrew's in Pukekohe - but halls, hospitals and even theatres were also built to recognise war efforts and give thanks for peace.
Ringer had come across examples of folk art, which incorporate some significant works by well-known artists that have gone missing from the canon.
These include some seemingly forgotten paintings by WWI artist Horace Moore-Jones on the Onehunga Soldiers' roll of honour, two unlisted buildings by well-known Maori architect John Scott at Haumoana War Memorial Park and a massive but little-known shrine designed by the Auckland artist and sculptor Richard Gross, which forms part of the Matamata Civic War Memorial.
"There are no doubt other examples yet to be discovered."
A register of 453 public WWI memorials was initially compiled by historian Jock Phillips who, with fellow writer/historian Chris Maclean, wrote the 1990 book The Sorrow and the Pride: New Zealand War Memorials. Phillips last year released the book To the Memory - New Zealand War Memorials, which expanded on his earlier research.
Despite these efforts and the work by volunteers like Ringer, gaps in the record remain. The Ministry of Culture and Heritage says on its website, nzhistory.govt.nz, that it is always keen for people to check if local memorials are on the register and to contribute information about them.
Meanwhile, for the first time in many years, the magnificent stained glass windows in St David's, the "soldiers' church" in Khyber Pass, will be lit on Monday evening, before Anzac Day as part of the city's continuing commemorations of the centennial of WWI.
The free public event is from 6pm-7pm on Monday, 24 April at St David's Memorial Church, 70 Khyber Pass Rd, Auckland.
