The Hammers scored a last minute try via Willie McGoon, ensuring that West Coast’s potential dream close to the season – they had beaten Wanganui the week before – would not continue.
West Coast have never contested the Meads Cup Final, while traditional powers Wanganui will for the first time not contest the major trophy in the competition.
For Mid Canterbury, two-time Meads Cup finalists, a return to the big deciding match for the first time since 2009 is a welcome achievement for coach Glenn Moore, with the former Highlanders and Otago mentor looking to win a title in his first campaign.
North Otago, the only side to beat the top of the table finishers, will meet Mid Canterbury in Ashburton in the final, with the Old Golds beating Wairarapa Bush in Oamaru 48-34.
The Lochore Cup, the second tier trophy, will be contested between South Canterbury and Buller in Timaru.
The replay of last season’s final gives Buller the chance to win consecutive crowns, and will enter in form after posting 40 points against Wanganui.
South Canterbury accounted for Thames Valley, and will be looking to add the trophy to the Hanan Shield, which they currently hold.
Three of the four finalists compete for the famous Shield donated by the Mayor of Timaru in 1946, giving the South Island a near clean sweep of the Pink Batts Heartland Championship in 2013.
