Last year Equidays had more than 23,000 visitors through the gates at Mystery Creek, more than double the number five years before.
With the event now in its seventh year, Ms Hardie says they're always looking to add to what they offer.
"We get so much amazing feedback after each event, and we've just gone from strength to strength each year." she says.
This year Equidays runs from Friday-Sunday, October 13-15 at Mystery Creek Events Centre. Since its inception in 2010, Equidays has grown into a world-class event, endorsed by Equestrian Sports New Zealand (ESNZ) and event ambassadors - the popular Wilson Sisters.
Education is a big focus of Equidays, alongside its values Entertain, Equip and Empower. This year there are 16 visiting clinicians and more than 40 hours of clinics per day, along with more than 200 exhibitors where visitors can purchase equine equipment.
Each year international clinicians host a variety of teaching workshops for riders and the public.
Among the clinicians this year are Rob Ehrens, Olympian and coach of the current world show jumping champion, and Kyra Kyrklund, who is a six-time Olympic medallist and world champion dressage superstar.
A third night show has also been added to the line-up of entertainment.
"We've usually had night shows on the Friday and Saturday, but due to demand we've now added a Sunday night event," says Ms Hardie.
The night shows feature top riders racing and jumping, and performances from world-leading equine entertainers.
Vicki, Kelly and Amanda Wilson will host the inaugural 'Top Talent' competition, where selected participants impress the crowd with their horsemanship skills, and Texan father-and-son duo Craig and Cole Cameron will lead the 'Cowboy Challenge' - a competition for western riders.
Other performers include Dan Steers - aka Double Dan - and his wife Pia in the Equitainment Extravaganza, and Kapiti Vaulting, who will perform alongside adagio dancing duo Silhouette.
