Another highlight of the weekend is a thanksgiving service and candlelight ceremony arranged by Denis Mark. The ceremony, which is usually held before Anzac Day, is this year part of the RSA's celebrations to honour the past presidents as well as all who served in both World Wars and other modern conflicts.
The service in the Levin RSA clubrooms on Sunday starts at 11am. All are welcome.
Other features of the weekend are an Anzac Biscuit baking contest and a centenary social event on Saturday evening.
The outside of the club building has had a makeover before the big weekend. Resene Paints donated the paint and the work was done by member Brian Kaye assisted by another volunteer, John Craig.
Inside, the club has been decorated with flags and bunting to welcome visitors for the celebrations.
A centenary booklet has also been produced for the weekend.
"It's only been a few years since the club faced closure, but here we are celebrating 100 years, thanks to all the volunteers who have kept the club going," Kaye said. "I think our past presidents would be very proud of what they have achieved."
Marshalling for the street parade is at 10.30am and the parade is timed to leave the Levin and District Memorial Hall at 11am.
It will turn left into Queen Street, then around the roundabout to Salisbury Street to recognise the Levin RSA Bowling Club and turn right into Devon Street to the RSA Clubrooms where the parade will finish. Formalities and speeches will follow.
