"We can't make as many mistakes as we did against Harbour - in the end got through on Ash's boot so we want to create more opportunities to score tries this week."
Vessey is back in the starting line-up this week - one of 10 changes made to the side that took the field against Harbour.
Injuries have played their part but Adriaan Ferris said he and Derren Whitcombe have selected the team that they think will cause Tasman the most problems in Blenheim.
"We looked at Tasman and tried to pick a team that would best take advantage of the vulnerabilities we saw in their team," Ferris said.
Kerikeri's Jack Ram gets his first start, with an injury cloud still over Dan Prior. Samisoni Fisilau returns at halfback with Rhyan Caine not 100 per cent, giving Mid Northern's Sonetane Takalua a chance off the bench.
