The Steamers defence last weekend, especially in the second half, was much improved compared with their opening four games.
Steamers coach Kevin Schuler was upbeat and said the players had rested up well after a big schedule last week.
The players would need to be really physical against the big Auckland pack tomorrow, he added.
"First thing is we have got to be pretty confrontational.
And from our point of view we have just got to be confident in our systems and structures ... and build some pressure."
He said, after their victory last weekend, it would give them a lift knowing that first win of the season is in the bag.
"The good thing now is a little bit of a weight will be lifted off their shoulders and maybe [this Saturday] we will see some real expansive Bay rugby, too." The Steamers have named an almost identical side to the one which defeated North Harbour.
The biggest change will see captain Culum Retallick return to the starting side after being rested and coming off the bench last weekend.
Steamers dangerman Tino Nemani will also return to the wing while Leroy Van Dam will start at fullback, after a good performance there last weekend.
Meanwhile, Auckland coach Paul Feeney has made four changes to his starting line-up to face the Bay. Auckland scored 25 unanswered points to steal victory against Wellington last weekend.
Youngsters Blake Gibson and Leon Fukofuka are both promoted to the starting XV. Ben Lam replaces the injured Vince Aso on the wing, while Liaki Moli's strong cameo from the bench on Saturday also sees him return to the second row.
