That eventuality looked a long way off as Hawke's Bay struggled to assert themselves in the opening half. With the wind on their side, the Magpies enjoyed the best of field position but continued to cede possession to the Stags, with errors in open play and at lineout time proving their undoing.
Willis Halaholo grabbed the game's first try, exploiting deficiencies in the Hawkes Bay defence, before Guy Millar dotted down to put the home side in complete control. But a crucial try on the stroke of halftime from Robbie Fruean pulled the Magpies within five heading into halftime and, when Mason Emerson crossed after the break, the Bay were soon in front.
The double strike owed some to poor spot tackling from Southland but Hawke's Bay looked a different side while playing into the elements, a feeling that was only enhanced when the calvary came off the bench.
Two tries in 10 minutes from Ryan Tongia secured the bonus point and, despite the wind causing complete havoc with Ihaia West's clearing kicks, the Magpies were able to hang on.
Southland 28 (Halaholo, Millar, Molloy tries; Sopoaga 3 pens, 2 cons)
Hawke's Bay 35 (Fruean, Emerson, Tongia 2 tries; Elkington 3 pens, 3 cons)
HT: 18-13
