On my last visit to New Zealand an interesting conversation ocurred between myself and the immigration agent.

Agent: What is your purpose for visiting NZ?
Me: Visiting a friend.
Agent: What is your friend's address?
Me: I don't really know since they are picking me up but I have their phone number.
Agent: How long are you visiting?
Me: 9 days.
Agent: Ok. Do you have sufficient funds to support yourself in NZ during this stay?
Me: (opening my wallett with various CC's) Is this sufficient?
Agent: Are all these gold cards REALLY real?
Me: To the best of my knowledge they are. Would you like to check them out?
Agent: No, it's OK. Enjoy your very brief stay in NZ, Sir and welcome back anytime!

Looks like smooth sailing to me.
