Mutch (39), is the winner of the World individual title in Masterton in 2012, a teams title in Ireland two years later, and the Golden Shears Open title in Masterton in 2015.
He will bypass Corwen to compete at the Antrim Show in Northern Ireland and the Black Isle Show back in Scotland. These are the the last two shows in the Scottish Circuit which Mutch must win if he is to represent his native Scotland at a seventh consecutive World Champion in France next year.
In between he will return to New Zealand where he and his wife farm together at Whangamomona.
