I had next to no great susets while in New Zealand. Getting a great sunset in Queenstown was a big wish of mine just because the setting is so dramatic and with some great vantage points available, I was really hoping to get some great colour.
My first two nights yielded mostly overcast skies with a little bit of sun peaking through. After 2 days in Milford I spent one more night in Queenstown before flying back to Auckland. I'm really glad I did!
