Berlin and the cost of living

We are in Berlin. We are staying with a family who hosted Finn for 9 months when he was last here: Uver and Katerina. They are very friendly and put on a barbecue to welcome us.

I have decided not to attend the England game.

What is the cost of living in Germany compared to NZ. Here is a quick price comparison based on the things I buy:
- Fuel: more expensive. It's NZD $3.08/L for 95 octane (or 1.75€ per litre). You would pay about NZD $2.50 in New Zealand?
- Bananas: the same. About NZD $0.50 each.
- Chocolate milk: slightly cheaper. NZD $2.20 for 400mlBaca lagi
