"We know we're a good team. We know we're good enough to win these games," said Rojas. "We don't want to go these future tournaments and just be there. We want to make some noise. We want to push ourselves in every camp and on every tour."
"Obviously we're not underdogs in Oceania so it's more about after that but we need to start getting the mentality that when we go to play a football game, we're on the same level and on the same pitch so we can't think of ourselves as a lesser team," he said.
In the past, New Zealand sides have on occasion found it harder than expected to subdue their Pacific Island neighbours. Rojas was part of the side that famously lost in the semifinals of the OFC Nations Cup in Honiara in 2012.
"We no longer [want to] go into these games and come out bruised after a really tight game. We want to make sure we go in and dominate from start to finish and really stamp our authority on Oceania," he said.
"[It's about] zoning in on the mental aspect and the fact that we're the biggest team in Oceania and we should be playing the sort of football against the other teams that shows that status.
"We'll be trying to do that on this trip and in the next qualifiers and building towards becoming a better football team."
Rojas also hopes that mentality will become evident when New Zealand face bigger footballing super-powers than Fiji.
