Extremely racist and short minded people working at the passport control. I was on a trip to australia and before flying back to Europe went for two days to visit a friend in Wellington. I have a European Union Eastern European passport. The immigration people decided that I wanted to stay illegally in New Zealand. They asked me to unpack all my luggage, telling me that this was a routine procedure and I was randomly selected to be checked if I am not carrying drugs. I spent more than two hours in the arrivals. I be been to New Zealand before and flew from Auckland where the passport control agents were more civilised and friendlier to tourists.
