Compared with sombre Brazilian supporters slumped on their bar stools, the Germans were draped in their national flag, celebrating wildly after each goal and chanting ''Deutschland'' over and over.
Simon Gruenefeld, of Kassel, said people back at home would be ''out of their minds'' at the result, and would be unable to sleep after watching the game.
''This is ridiculous; this is unbelievable.''
Milan Waldeck, also of Kassel, said Brazil appeared to have
been mentally ''destroyed'' after the first three goals.
He expected the Netherlands to beat Argentina in this morning's other semifinal, and expected the final to be much closer.
''After this, there is huge pressure on Germany.''
At Ratbags bar in the Octagon, the mood was mostly sombre.
But the result, clear as the game drew to a close, produced the opposite reaction from German fan Malte Lambers.
Mr Lambers, who has lived in Dunedin for six years, was feeling ''pretty good'' when the German team was up 6-0.
''I'm a bit surprised, but not really. I'm quite optimistic.''
Seconds later, Andre Schuerrle scored his second goal in the 79th minute, to take the score to 7-0.
''Now I'm surprised,'' Mr Lambers said, once celebrations died down.
