Three weeks sounds like a long time until you get here and realise you will want to see everything! Autumn is the best time to visit - February-March - as the kids are back at school and the weather is USUALLY warm, dry and settled.
I'd be tempted to fly in to Christchurch and tour up the island - don't miss Central Otago and Marlborough, then pop over to Wellington for a day or two, and head up the east side of the North Island, Wairarapa, Hawke's Bay, then across to the Bay of Plenty and then up to Auckland. If you have time, head north to the Bay of Islands, but that way you should at least get a good taste of the country.
One place to visit? Mmn, that's a hard one - I reckon you'll love just about everywhere, depends on what you like - lakes, rivers, mountains, forests, cities - we've got it all!
Yes, I am pedantic about spelling and grammar so get used to it!
