I have just finished the grand explorer finishing in christchurch.
Words cannot desrcibe the beauty ive seen, the many different friends i have made.
Bay of islands was spectacular, i recommend the sailing.
Waitomo- dont do black water rafting if your afraid of the dark or unfit.
If its wet in rotorua dont do an outdoor optional. Taupo definitely do the huka jet and scenic flight.
Wellington was awesome.
Queenstown went off, definitely recommend bungee jumping or snowing if your into that.
Fox glacier- well seeing as my helihike was cancelled i hiked- also another one of those things you have to be pretty fit for.
Overall i can say this is the best holiday ive ever had and pray you get nikki and nigel the best tour manager and tour driver in all of nz
