Hobbs and No 8 Steven Setephano -- in for the injured Nasi Manu -- were the two changes confirmed today for the starting 15 from their opening round defeat to the Crusaders.
Berquist is expected to be sidelined for one week with a hamstring strain, opening the door for Hobbs who produced an impressive two-try performance off the bench in Christchurch.
Setephano was promoted to the starting 15 due to a knee injury to Manu who is expected to be out for four weeks.
The only other change was on the bench, where another promising five-eighth, Robbie Robinson, awaits a potential Super 14 debut.
