Five hundred hours is tight for an itinerary this ambitious. Here's the plan. Young Englishpersons Richard Roberts and Kate Wastling will set off from Auckland, drive to Paihia, then fly to Christchurch to see Richard's brother, James.
Richard: "We stay there a night. Get a campervan for a week then head to Nelson. Do the Abel Tasman. Then we drive back down - to Queenstown - and stop for a bit. We're doing the Routeburn Track for three days. Then we spend another week going from Queenstown to the Catlins. Via Dunedin - I've got a friend there. Then it's back to Christchurch, up to Blenheim, then back to Christchurch again."
All this in three weeks. Goodness. "You're selling this to me!" Kate says, laughing.
Richard smiles. The 27-year-old is one of those quiet, terribly nice and ever-so-slightly-awkward Englishmen (of the Colin Firth genre). He's tired and his bags have just been disembowelled by New Zealand Customs - but he's too polite to refuse further interrogation from the Herald.
