The dreary proceedings were replaced by free-running rugby after the break, with the match roaring into life in the 49th minute.
After an early Hollinshead penalty, it was Southland who crossed for the first try of the game, through number eight Bill Fukofuka. Winger Tauasosi Tuimavave busted two tackles on a 30 metre dash, before recycled ball from the breakdown saw a Willis Halaholo cut-out pass find Fukofuka, who crashed over in the right hand corner.
That was the closest Southland would get, with the 12-10 margin quickly increasing to 26-10 through two long-range Steamers breakaway efforts.
First, a blocked Stags kick led to Steamers fullback Te Rangi Fraser pulling off a kick and chase from halfway, winning the race to dot down and immediately push back out the lead to a nine point margin.
The hosts then increased the lead to an insurmountable margin with 15 minutes remaining, with winger Chase Tiatia picking up a Southland knock-on, shedding weak tackles on a 50 metre dash to the line to notch his third try of the campaign.
All Black flanker Sam Cane had an efficient game for the Steamers, making several turnovers at the breakdown, while Southland hooker and former New Zealand U-17's representative Dillan Halaholo had an excellent performance, showing impressive mobility and a strong workrate.
