The Southland Shears and the Dannevirke Shears have joined the list of cancellations now affecting more than a third of the competitions on the 2021-2022 Shearing Sports New Zealand calendar.
Committees from the shows made the decisions at meetings on Tuesday.
This brings the number of competitions that have been cancelled due to Covid-19 to at least 20, including 11 in the New Year and glamour event the Golden Shears.
Originally, 59 events sat on the calendar at the start of the season.
The Southland Shears, incorporating the New Zealand Crossbred Lambs Shearing and Woolhandling Championships, were to have been held at Winton Racecourse on January 15, and the Dannevirke competition was to have been held on February 4.
Shearing Sports New Zealand chairman Sir David Fagan acknowledged the testing times for organisers who had to consider how late in the planning they can go, before making the ultimate decision - usually the point at which pre-competition costs started accruing.
Other factors include whether there were enough people on the day for the staging of events based on regulations, the unique nature of each facility, and the consequences of having to cancel in the last days - or even on the day of the event.
Addition considerations are whether events could go ahead with reduced support, extra costs and in a reduced format, such as A and P shows downsized to competitor-only events.
"Ultimately it's all about safety, and all of the committees are desperate to keep their competitions going for the benefit of the competitors and the sponsors and supporters – if they can," Fagan said.
"For some, there are no options, and all around it is stressful and all are disappointed when they have to call off their events."
The PGG Wrightson Vetmed National Shearing Circuit is still on, with qualifying rounds at Alexandra, Waimate and Christchurch completed in October-November, and the last two rounds at Marton and Pahiatua still programmed for February.
Its committee is considering options on where to stage the semi-finals and final, which were to have been at the Golden Shears.
The stresses on the committees were highlighted by Southland Shears chairman Mike Hogan, whose show was due to run just a day after Lumsden's Northern Southland Community Shears and national Longwool Championships, which are still scheduled for January 14.
Dannevirke shearing committee convenor Jane Leogreen said the Southern Hawke's Bay event's cancellation was particularly disappointing, as it was a part of a three-day Waitangi Day Weekend event.
The Rangitikei Shearing Sports in Marton the next day (February 5) and the Aria Waitangi Day Sports are among those still going ahead.
Seven competitions were held without general public admission in the South Island, but no competitions have yet been held in the North Island; however, Horowhenua show organisers are still hoping to run their shearing-only event on January 23 in Levin.
