The New Zealand Agricultural Show in Christchurch will be cancelled this year because organisers say it's not financially viable.

The Show has been held annually by the Canterbury A&P Association at the showgrounds in Christchurch each November since 1863.

Livestock judging and competitions would still be held this year, without the public crowds, as was the case in 2020 and 2021 during the pandemic.

Association board chair Stewart Mitchell said it was sad news and the show's current business model was under review.

Mitchell said twelve months of costs but only three days of revenue was not a good model by anyone's standards.

"The decision to postpone the 2024 Show was a very disappointing one to make, but after several challenging years it gives us an opportunity to completely rethink our strategic direction.

"After two Covid years and a recent financial loss in 2023, the Association's financial reserves are limited, and with highly variable income streams, we are unable to sustain the risk of another loss in 2024."

Mitchell said they were now focused on consolidating revenue to allow the show to return in 2025.

Canterbury Agricultural & Pastoral Association general committee president Bryce Murray acknowledged it was sad news.

"While this is frustrating, we promise to be back stronger and better than ever next year."
