The 22 presidents who have served the Levin RSA will be honoured in a street parade to start celebrations for the 100th anniversary of the association on Saturday.
The families of all but four will take part in the parade and 16 will answer the roll call before the parade and carry a sign with each president's name.
"We are so pleased to have been able to track down so many families," current president Wayne Kaye said. "And it is fantastic that Carolyn Sutherland, daughter of the late Ken Dalzell, is coming for Australia for the celebrations."
As well as the presidents' families there will be two bands, community groups, vintage army vehicles and vintage cars transporting older RSA members and veterans.
Kaye said veterans, wearing their medals as on Anzac Day, and families with RSA connections are also welcome to join the parade.
