The Highlanders scored four unanswered tries to upset Super Rugby leaders the Sharks 34-18 and grab a bonus point away at Durban on Saturday morning, to move firmly into contention for an end of season playoff place.
Richard Buckman, Aaron Smith and Shane Christie all crossed over in the first half before Malakai Fekitoa
cut through the home defence for a bonus point fourth try with 10 minutes left.
The first five eight Lima Sopoaga produced a 100 percent return from the boot with four conversions and two penalties as the Sharks suffered their first home defeat of the season and only their second loss in nine outings.
The lethargic Sharks paid the price for a poor performance filled with handling errors and wayward tactical kicking.
