The Tall Blacks will fly to Barcelona tonight with renewed self-belief.

New Zealandâ s through to face Lithuania in the round of 16 at the Basketball World Cup after winning their last two group games.

Tall Blacks forward Isaac Fotu says they were pretty down after losing to the Dominican Republic in their second game of the tournament.

"But to bounce back and win these two games, I think that's given us a confidence booster and shown that we can play with any team in the world.

"Maybe apart from USA and Spain."

New Zealand will have two full days to prepare for Lithuania, with their game on Monday morning.
