The short version.
New Zealand is long, thin and mountainous, and it is two separate islands with a strait between them. Every one of those facts costs time that a map does not show. A distance that looks like a comfortable morning can be most of a day once the road starts climbing and turning.
The single most common planning error here is treating driving hours as though the roads were straight. They are not, and the authority says so.
Driving, and the license question.
The UK Foreign, Commonwealth and Development Office states that a photocard driving license can be used to drive in New Zealand for up to 18 months. That is a generous allowance by international standards and it is the kind of rule that varies by the license you hold, so check your own entitlement rather than assuming a rule written for another country's drivers applies to you.
The same advice records that highways can be narrow, winding and hilly. Read that as a time calculation rather than a difficulty rating. Two lanes, no shoulder, frequent bends and a gradient are ordinary conditions on roads that carry tourist traffic, and they turn an average speed into something well below what the distance suggests.
Crossing between the islands.
The two main islands are separated by Cook Strait, and moving between them is a scheduled crossing rather than a bridge. That shapes an itinerary more than anything else on this page: the crossing has to be booked, it takes a meaningful part of a day, and a vehicle traveling with you is a separate consideration from a passenger ticket.
This page does not publish sailing times, fares or frequencies, because no source in this cluster's research register carries them. Take those to the operators directly, or ask us and we will build the crossing into the plan with the current schedule in front of us.
What the register does not cover.
New Zealand's transport agency was unreachable when this cluster's sources were checked, so there is no official road rules citation here and this page does not attempt one from memory. Speed limits, alcohol limits, and the rules on passing and on one lane bridges are all real and all worth knowing, and the honest thing to say is that you should read them on the transport agency's own site rather than take them from a travel page.
What is sourced is the shape of the problem: roads that are slower than they look, on a license that is likely to be valid for longer than your trip.
Getting to the walks.
Many of the places visitors most want to see are reached by road and then on foot, and the Department of Conservation asks visitors to always be prepared for your trip. That applies to the drive as well as the walk. A trailhead an hour beyond the last town is an hour beyond fuel, food and a phone signal, and the return drive happens when you are tired.
How to plan it.
Halve your instinct about how far you can cover in a day, then build the itinerary around fewer bases and more time at each. Book the strait crossing before the accommodation on the far side. Leave the alpine and coastal drives for daylight. And tell us where the fixed commitments are, because the right plan usually removes a leg rather than compressing one.
