The nervous All Whites suffered stage fright on Sunday against the big names of Spain and were four goals down after 24 minutes before they woke up and made a match if it.
Herbert, who played for New Zealand at the 1982 FIFA World Cup™ finals, said it had taught his team, which rarely gets to play such top class opposition, some hard lessons.
"The guys are obviously disappointed. There were too many individual errors, but they will take it on the chin," he said.
"We're not surprised by the Spanish performance, I think they are the favourites to go on and win the tournament."
New Zealand, the Oceania champions, are playing in their third FIFA Confederations Cup, but have yet to take a point from seven games.
"We haven't got a point and there's certainly a burning desire to get that," he said.
"But the competition itself is enough motivation for us. It's a new day today and we'll bounce back," said Herbert.
