Most people see one island and call it New Zealand

Flights from India arrive via Singapore or the Gulf, usually in the morning after a long overnight leg. New Zealand immigration is strict: declare everything organic, fill the biosecurity card honestly, and keep the queue moving. Check in, sleep off the worst of the jet lag, then walk the Viaduct Harbour and Wynyard Quarter in the evening light. The water is the point of Auckland. Dinner on the wharf — fish, whitebait fritters, a glass of Marlborough white — makes an easy first night.

Up the 328-metre Sky Tower for the two-harbour view — on a clear day you see Waiheke to the east and the Waitakere ranges west. Then across town: the Auckland Domain and its museum holds the country's finest Maori and Pacific collection, and Mount Eden's volcanic crater gives you the city skyline without a ticket. Mission Bay in the afternoon: sand, a flat-white, nothing pressing. Dinner in Sandringham, where the Indian and Sri Lankan restaurants are better than most hotel menus will admit.

If you want a morning with a story, the All Blacks Experience in the city centre is a guided walk through Maori culture and New Zealand rugby history — ninety minutes, and the haka room alone is worth it even if you have never watched a match.

A forty-minute ferry from the Britomart terminal crosses the Hauraki Gulf to Waiheke — vineyards, olive groves and beaches that feel nothing like the city. Oneroa village in the morning, a vineyard lunch with tastings for those who want them (the Rosé is the local signature), and the clifftop walk at Cable Bay before the afternoon ferry back. This is one of the rare days when you genuinely do not need a driver.

South out of Auckland through green Waikato farmland to the Waitomo caves, where a silent boat drifts under a ceiling of thousands of glowworms — Arachnocampa luminosa, a creature found only in New Zealand — and the river disappears into darkness lit only from above. It takes about forty-five minutes underground and no amount of photographs prepares you for the actual ceiling. Continue south to Rotorua by late afternoon. You will smell the sulphur before you see the lake. Walk the steaming ground of Kuirau Park before dinner — it is a public park, it is free, and it is genuinely strange.

The guided small-group tour from Auckland — Waitomo, Rotorua and Te Puia in one long day — is the sensible option if you have not pre-booked a self-drive: the group size is capped, the driver knows the order, and you arrive with energy left.

A morning in Te Puia geothermal valley: the Pohutu geyser throws water to thirty metres on a good day, boiling mud pools plop and hiss at arm's length, and the national carving and weaving schools run inside the same site — Maori craft taught, not staged. The evening is the trip's set piece. A Maori village welcome, the haka performed a few feet from you, and a hangi dinner lifted steaming from the earth oven — meat and root vegetables cooked for hours on heated stones, smoky and impossibly soft.

Book the National Kiwi Hatchery tour in Rotorua for a spare hour before check-out tomorrow: sixty minutes inside the most successful kiwi conservation programme in the world, and you will actually see the eggs, the chicks and the science behind it — not a zoo, a working hatchery.

A fifty-minute flight over Cook Strait swaps islands and saves two days of driving and a ferry crossing. Christchurch by early afternoon: the punts on the Avon River drift under willow trees at walking pace, the Botanic Gardens are free and large enough to lose an hour in, and the rebuilt city centre — which took a decade to recover from the 2011 earthquake — is now a genuinely handsome low-rise place worth a proper walk. Ride the restored vintage tram loop if the legs are done. Dinner in the Riverside Market.

Out through the Port Hills to Akaroa on Banks Peninsula — about eighty kilometres, an hour and fifteen minutes — a harbour town inside an old volcanic crater that the French attempted to colonise in 1840, narrowly losing the race to the British. The street names survived; the boulangerie has not, but the cafes have. A harbour cruise in these waters looks for Hector's dolphins, the world's smallest and rarest marine dolphin, found only along the New Zealand coast. Back over the hill by evening with the Canterbury plains spread below in the last light.

The full-day Akaroa sightseeing tour from Christchurch handles the driving and the harbour cruise together, which matters on a road that rewards looking out the window rather than at the GPS.

Three hours southwest into the Mackenzie basin, where the land dries to gold and the rivers run milky with glacial flour. Lake Tekapo hits you before the car stops: the water is a turquoise that reads as unnatural, produced by fine rock dust suspended in glacial melt. The Church of the Good Shepherd sits on the shore — small, stone, photographed a thousand times a day — and in November and December wild lupins line the water's edge in pink and purple. Soak in the hot pools as the light goes. After dark, step outside and look up: the Mackenzie basin is a certified dark sky reserve, and the Milky Way is not a metaphor here.

Along the shore of Lake Pukaki — another turquoise lake, if anything more vivid than Tekapo — to Aoraki Mount Cook village, with the 3,724-metre summit filling the windscreen on a clear day. Walk an hour of the Hooker Valley Track to the first swing bridge: glacier views, alpine flowers, cold air that cuts. Lunch at the village, then south through the Lindis Pass — tawny high-country tussock — and the Kawarau Gorge, where you pass the original Kawarau bungy bridge, into Queenstown by evening. If the group did not pre-book the Christchurch day tour, this day handles Tekapo and Cook together from a different angle.

The Mount Cook, Lake Tekapo and Tasman Glacier full-day tour from Christchurch is an alternative if you prefer to move your luggage directly to Queenstown on a separate shuttle and ride this circuit without the gear.

The Skyline gondola takes eight minutes to climb Bob's Peak; the view over Queenstown, Lake Wakatipu and the Remarkables range is worth the cable car ticket alone. The luge runs at the top are faster than they look, and adults reliably enjoy them more than they planned to. The afternoon is yours on the lakefront — browse the adventure menus, book a Shotover jet boat, or simply sit on the wharf. Today is also the day to visit Kiwi Park if children or first-timers want to see the national bird up close: twenty-plus species of native wildlife in five acres, family-run, ten minutes from the centre.

The Queenstown skydive — 15,000 feet, the Remarkables and the lake below — is the day's optional headline. Book it for the morning when the clouds are more likely to be clear.

Leave Queenstown by seven. The drive through Te Anau and into Fiordland takes about two and a half hours, the last stretch through the Homer Tunnel — a single-lane bore through the rock face, no lights, dripping — into a world that does not look real. Two hours on the water aboard the RealNZ cruise: Mitre Peak goes straight up 1,692 metres from the surface, seal colonies sprawl on warm rocks, and the boat noses under waterfalls that drench the bow rail. If rain arrives, better: the cliffs run with hundreds of temporary cascades that vanish in dry weather. Back to Queenstown by eight or nine. Long day, non-negotiable day.

Book the Milford Sound cruise in advance: it fills weeks out, especially in October and November. The RealNZ classic cruise is ninety-odd minutes on the water with multilingual commentary and a place at the bow rail worth protecting.

Morning in Arrowtown, twenty minutes away: a gold-rush town whose main street has barely changed since the 1860s, with a preserved Chinese miners' settlement in the willows by the Arrow River that tells a harsher chapter of the same story. Lanes made for slow walking, a good pie, a coffee. The rest of the day is unscheduled on purpose. A Gibbston valley wine stop on the drive back, a lake cruise on the vintage TSS Earnslaw steamship, or simply the lakefront again with nothing left to tick. Pack tonight; the airport is ten minutes away.

Breakfast with the Remarkables still there. The transfer to Queenstown Airport takes ten minutes — it sits in a mountain bowl and every landing is a spectacle; every departure is the same. Connect via Auckland or an Australian gateway for the India leg. New Zealand imposes no departure tax at the airport, but biosecurity checks on bags can run long if you bought fruit or untreated wood products.
