Herrera also revealed their plan to take the capacity crowd out of the equation in the early stages.
"We want to score early, to wipe out New Zealand's [away] goal," said Herrera. "We have an advantage from the first game but nothing more than that. The game starts again [tonight]."
Asked for any negatives from the comprehensive win in the first leg, Herrera nominated the concession of the Chris James goal as the most disappointing part of Mexico's performance and emphasised that there couldn't be a repeat of that tonight.
Herrera will field the same line-up that took the field last week, while All Whites' coach Ricki Herbert has made five changes.
Despite Herrera's assertions, expect Mexico to take a canny, cautious approach to tonight's game. They will look to absorb the early onslaught from the All Whites, soak up the pressure and then, once the home side commit forward in numbers, attack on the break.
Herrera also emphasised that his team have enjoyed the friendly relaxed environment that Wellington has offered over the last few days, a huge contrast to the kind of reception and environment that the team face when they play around the Concacaf region, especially in Central America. Tonight's match kicks off at 7.00pm.
