Otago made it two wins from two to begin their Mitre 10 Cup campaign as they held off a brief Wellington fightback to prevail 44-21 on Thursday.
The home side ran in four unanswered tries in the first half at Forsyth Barr Stadium, taking a 28-0 lead into the break before Wellington threatened what would have been a brilliant turnaround.
The visitors crossed three times after the restart, but Otago did enough to keep them at bay, securing a second bonus point win after their 40-17 victory over Southland last time out.
The first try arrived in the eighth minute when Teihorangi Walden's offload set Matthew Faddes away, and the lead was doubled after Tom Franklin's pick up and go was awarded by the TMO.
Sam Anderson-Heather's score from a rolling maul and Jack Wilson's intercept try put Otago in a commanding position at the break, but Wellington came on strong in the second period.
Wes Goosen got them on the board shortly after the restart with a multi-phase move finished off in the left corner, only for Otago to hit back quickly through Michael Collins.
Wellington's second arrived courtesy of Shaun Treeby, and Matt Proctor's superb solo score brought the visitors back to within two tries, but a pair of Fletcher Smith penalties and another three points from Scott Eade's boot gave Otago the breathing space they needed to see out the win.
