Hi Sam i will not be allowed to travel that far can do only 3-4hrs on a plane so i hope you have a great time my family who go bring plenty back for me to have a look at when we see each other.It's a wonderful place and in some respects the land that time forgot. We're fortunate to be able to go most years and we've toured most of the North and South Island - just by car.
We've also been 'caravaning' with them. We get to use the van and they stay in tents. The sites have been very good - a little busy but well maintained.
