"It's representing Tauranga . . . It's a pretty important day for New Zealand, and the rest of the world," he said.
"Everywhere else has their equivalent of Anzac Day on Remembrance Day. . . It's a big day around the world."
Armistice Day commemorates the signing of the armistice agreement which signified the ending of World War I. It was signed on November 11, 1918 at 11am.
Moss said the service would start at 10.55am, with a march up to the cenotaph before new mayor Tenby Powell formally welcomed the public.
After the welcome, there will be prayers, and then the national anthem will be sung, led by Mount Maunganui College student Saffron O'Donnell.
Moss said representatives from the French and Australian embassies in Wellington would be present at the service, to commemorate New Zealand soldiers liberating the French town of Le Quesnoy in November 1918.
Greg Moyle, chairman of the New Zealand War Memorial Trust Le Quesnoy, has been invited to speak at the service.
Moss said Tauranga City Council was instrumental in enabling them to hold the service.
"The council have actually [paid] for a traffic management plan and portaloos and that sort of thing . . . It's a joint effort, I think."
