I have done this tour and everyone but me just flopped on the beach after the fab but tiring whizz around New Zealand! I did a whole day trip trip up the river to a remote village in a sort of motorised canoe....bit hair-raising but fun. If you are staying at The Warwick there is not a lot else within reach as it is a bit out of the way! I think, with hindsight, I would not have bothered with the add-on tho as I thought it was rather expensive for the little time spent there. NZ was great tho!!

Cheers

Many thanks, most helpful.
