Games' spokeswoman Pat Hadlee said that even after more than a century, the event seemed to evolve each year in terms of preparation and visitor numbers.
She said 40 volunteers, mostly from Waipu including four provided by Volunteer Northland, will help out on Sunday.
"This year we do have an extra stage and anybody who wants to do a gig on stage can do it. It's very casual but it will be very spontaneous and dynamic.
"The Ballistic Blondes Skydive team will be landing in their kilts and this year we'll have a vintage Packard car from the Pioneer and Packard Museum, the Artan Tartan promoting their stuff, and the Waipu Cycleway group selling raffle tickets."
Ms Hadlee said the Waipu Caledonian Society hoped to host the World Highland Games in 2020, a massive event for the town.
People can dress up for the Tartan in the Park fashion event with prizes for best dressed.
The gates at Caledonian Park open at 9am on Sunday and there will be a traditional ceilidh in the Celtic Barn on New Year's night.
Lovers of highland piping can get a pre-games fix on New Year's Eve at the Helen McGregor Memorial Medley at the Celtic Barn at 7pm.
