Among the instructors will be Charlie Tapsell, former captain of New Zealand's Battle of Nations team.
The Princess Party will include medieval dancing and music, crafts, some archery and games.
"We are encouraging them to come dressed up in fairy princess outfits or as maidens - they don't have to be historically accurate," says Kris.
"It's something different and will take kids back to what it would have been like in medieval times."
The New Zealand Medieval Faire will be run over three days, with the Saturday coinciding with the Tauranga A and P Show.
For the past two years the faire has been held in Taupo. "This won't be like previous years (at the A and P Show) where there have been medieval demonstrations - this will be a lot bigger," says Kris.
Re-enactors from around the country will converge on the racecourse to act out battles from different eras including Roman and Viking times, plus there'll be a traders' market, craft demonstrations, plays and plenty of have-a-go activities.
"There will be some seige engines and catapults, an archery range and some big scale battles."
