It will be a show of speed, muscle and skill at this weekend's Pirongia Heavy Horse Shoeing Competition.
The annual event is at Pirongia Clydesdales from 10am on Saturday and will feature some of the country's best farriers.
The event is one of a few annual open days held at the popular Pirongia attraction, and visitors will have the chance to see the three-man teams of farriers shaping hot steel into horse shoes, and fitting them to the Clydesdale horses.
The competition is expected to attract some of the best farriers from across New Zealand who will compete against the clock and under the eye of an experienced judge.
Pirongia Clydesdales owner Nick van der Sande says most don't get the chance to see how horseshoes are made these days with the advent of machine technology, so it's a fantastic chance for the public to witness this age old art, and the great skill that is involved.
