Seven days ago, the hosts were left reeling after losing four semi-finals during the first week of the tournament.

However, today, they were jubilant as they dominated the rest of the field on a busy day at Burnside Bowls Club.

Led by skip Ali Forsyth, the men's four, which also includes Mike Nagy, Mike Kernaghan and Blake Signal, secured the Blackjacks' biggest win in the semi-finals.

They dismantled the Scotland team headed by Commonwealth and world champions Alex Marshall and Paul Foster 20-3.

Forsyth now has four world championships medals but will be hoping to win his first gold.

Standing in their way are defending champions Australia after they convincingly beat Ireland 22-10.

Meanwhile, Shannon McIlroy, a bronze medallist in 2012, beat Australia's Aron Sherriff 21-17 to qualify for Sunday's men's singles final.

He will meet Canada's Ryan Bester, who edged Scotland's Commonwealth Games champion Darren Burnett 21-20.

Jo Edwards has qualified for her fourth successive women's pairs final and has a chance to emulate Ireland's Phillis Nolan and Margaret Johnson as a three-time world champion.

Alongside partner Angela Boyd, they were in fine form from the start of their 13-11 semi-final win over England's Ellen Falkner and Sophie Tolchard.

The Kiwi pair will contest the gold medal on Sunday morning against Wales' Jess Sims and Laura Daniels, who defated for Scotland's Lauren Baillie and Lesley Doig.

In the fourth competition taking place this week, Wales and Australia will meet in Saturday's women's triples final after beating Malaysia 18-16 and South Africa 17-15 in their respective semi-finals.

The women's triples and men's fours finals are schedule to take place tomorrow while action at the championships draws to a close on Sunday when they men's singles and women's pairs gold medal matches are contested.
