"We've worked on the areas that were pretty obvious in terms of our defence but there will be no lack of motivation to play against the Crusaders.
"Our forward effort was good last week but we know it needs to go another notch.
"For us we have to do well on both sides of the ball. We had some individual lapses in defence and that's something we've worked on."
There is little on this match for the defending champion Crusaders, who are on an 11-match winning streak. They are guaranteed a home final should they progress that far but will want to retain the ruthless edge that saw them trounce the Highlanders 45-22 last weekend.
