The Shears began with a dinner on Thursday night, attended by about 200.
"Seeing so many old faces there ... it was a special night," Sir David said.
A highlight was president Warren White, a Waimate-based shearing contractor who has led the organising committee for 11 years, being made a life member. He was instrumental in joining forces with the Southern Canterbury A&P Association to have the 900sqm pavilion completed on time, after two years' planning and fundraising.
Mr White was also awarded the honour of shearing the first sheep in it.Sir David, who has been attending the Waimate Shears since he was in the senior competition in 1980 and won the main title 10 times, said he had some great memories of the event.
The pavilion was "a real credit to the committee and Warren White, and also the Waimate community and the A&P Association."
"It's an example to the rest of the country. Lots of these competitions have folded. It's too easy to let these things go."
Jack Fagan, of Te Kuiti, who won the Open Invitation Plate, said the pavilion was "one of a kind".
Committee executive officer Eileen Smith said it was "a great weekend". The number of shearers and woolhandlers competing was on a par with other years. Crowd numbers were well up thanks to the golden anniversary and the new amenities.
