Seriously thinking of heading to NZ in January with DS1 (then, almost 3) and DS2 (will be 13 months). We'll be there approx 12 days (inc travel). It will be a fly/drive holiday.

Given we're only there 12 days, we only want to do one of the islands. But which one?

For those familiar with the country, what do you reckon - North or South. And can you tell me what attractions will give us the best "bang for our buck", so to speak. Particularly as anything we do will need to be relatively kid-friendly and pram accessible.

Anything else we need to know?

TIA, Andie
