The country's oldest regional Returned Services' Association (RSA) turns 100 on Friday.
Three days of celebrations has been planned by the Kawakawa RSA to commemorate those who fought in World War I.
President Hector Davies says the RSA is central to the local community.
"We don't in Kawakawa itself have a marae as such - but the RSA facility is sort of the community hall."
Mr Davies says reaching a hundred years old is a major achievement for any organisation.
"It's crucially important that we can remain viable - not just for the RSA, but for the community."
The celebrations are being held with the Kawakawa Rugby Club, which turns 50 this weekend.
World War I ended in November 1918.
