RS999 - good luck for July 4th. I'll be flying out that day! I would get on the blower to NZ Immigration about the possible Visa types your wife could apply for sooner rather than later. You may have bureaucratic hoops to jump through so the earlier the better. CTC's visa situation is quite specialised and designed for one person so it's processed quickly, whereas your wife might have to be processed in a separate channel depending upon work and your kid etc.
Anyway, if it's any consolation, I've just hit 30 and there's a married guy of similar age heading out too, so the old dandies with responsiblities are making it in as well as the carefree young guns. Best of luck to you.
