New Zealand in December: weather, crowds, events and what to book early

December is when New Zealand switches into summer mode. The pōhutukawa trees bloom red along the northern coasts, the days stretch out, and the whole country starts counting down to the Christmas break. It is a great month to visit, as long as you understand that it is really two months: a calm, shoulder-season first half and a busy, booked-out second half.

This guide covers December weather by region, the school holiday rush, what closes over Christmas and New Year, the best events and what to book now. Dates are for December 2026, checked in November 2026.

Weather by region

NIWA’s long-term averages (1981 to 2010) give a good sense of what to expect. Coastal and northern places are mild; inland and southern places swing between warm days and cool nights.

Three things stand out. Napier and Christchurch are warm and fairly dry. The West Coast and Fiordland are wet whatever the season, so a raincoat is essential. And the Mackenzie and Central Otago can be warm by day but cold at night: a 7°C average low at Lake Tekapo means a proper sleeping bag if you are camping.

Snow and cold can still hit the mountains. DOC warns Milford Track walkers that snow, strong winds and heavy rain can happen at any time, and that avalanche risk on that track can extend into December.

Crowds and school holidays

The key date is the end of the school year. For 2026, the Ministry of Education says Term 4 ends no later than Friday 18 December, and summer holidays start no later than Saturday 19 December and run for five or six weeks. Term 1 of 2027 starts between 28 January and 3 February.

That splits December in two:

DOC gives a sense of the peak. White Horse Hill campsite at Aoraki/Mount Cook is busiest from Christmas to mid-February. Kidds Bush by Lake Hāwea is often booked out from Boxing Day to early February. And Tōtaranui in Abel Tasman switches to peak pricing from 26 December, with a $40 minimum nightly fee.

Insider tip: if your dates are flexible, aim for the first two weeks of December. You get early-summer weather, long evenings and Christmas events in the cities, without competing with the whole country for campsites and ferry space.

Where to go in December

Use the weather table to match regions to your plans:

• For warm, dry beach days: Napier (23.2°C average high, 53.5 mm of rain) and Nelson (20.7°C, 83.6 mm) are good bets, and Auckland’s beaches and islands are at their best once the pōhutukawa flower.
• For hiking: Roys Peak reopened after lambing on 11 November, and the Milford and Routeburn Great Walk seasons started on 1 November. Check DOC for snow warnings on alpine tracks early in the month.
• For lakes and stargazing: the Mackenzie (Lake Tekapo and Aoraki/Mount Cook) is dry at Tekapo, but nights are cold and Aoraki/Mount Cook gets 487 mm of rain in an average December.
• For drama in the rain: Milford Sound’s 700 mm average December rainfall means waterfalls everywhere. Go anyway, with a jacket.
• For Christmas atmosphere: the cities. Auckland, Wellington and Christchurch all run free Christmas concerts and parades.

Christmas and New Year closures

Public holidays over the 2026/27 break, according to Employment New Zealand:

Christmas Day is a restricted trading day. Almost all shops must close. Some can open, such as those selling essentials like food, drink and petrol, and some shops in a handful of exemption areas, which Employment New Zealand says are generally tourist resorts such as Taupō and Queenstown. Boxing Day is a public holiday but not a restricted trading day, so most shops can open.

In practice, plan for Christmas Day: buy groceries and fill the tank on Christmas Eve, and check opening hours for any attraction or tour you want to do between 25 December and 4 January.

Events

December is packed with free Christmas events and ends with the big New Year festivals. Each link goes to its page on our events calendar, with times, venues and tips:

• Coca-Cola Christmas in the Park: Christchurch on 28 November and Auckland on 12 December. Free concerts with fireworks.
• Christmas Show Parade, Christchurch: 5 to 6 December, with the parade on Sunday at 2 pm.
• Farmers Santa Parade, Auckland: 29 November, with a rain date of Sunday 6 December.
• A Christmas Cracker, Wellington: 12 December at Waitangi Park. Free.
• TSB Festival of Lights, New Plymouth: 19 December 2026 to 24 January 2027 in Pukekura Park. Free.
• Rhythm and Vines, Gisborne: 28 to 31 December, from $479 plus booking fee. Organisers say 2026 is the last held in Gisborne.
• Rhythm and Alps, Wānaka and Northern Bass, near Mangawhai: both 30 to 31 December.
• Waipu Highland Games: 31 December in Northland.

What to book early

Anything with limited capacity sells out over the holidays. In rough order of urgency:

1. Cook Strait ferries. If you are crossing between the islands with a vehicle in late December, book now. Our Interislander vs Bluebridge guide compares the two.
2. Campervans and rental cars. Holiday demand pushes rates up. Our campervan costs guide shows how much summer rates can exceed autumn ones.
3. Great Walks. Bookings for 2026/27 opened in May, and DOC says the Milford Track ran at about 95 per cent occupancy last peak season. Check for cancellations; our Great Walks guide covers the options.
4. DOC campsites. White Horse Hill, Kidds Bush, Tōtaranui and Moke Lake all need bookings, and no spaces are kept for walk-ins.
5. Festival tickets and nearby beds. Gisborne, Wānaka and New Plymouth fill up around their events.
6. Popular tours and cruises around Christmas and New Year.

Also note the Isthmus Peak Track near Wānaka is closed for fawning from 20 November to 20 December, so plan Roys Peak instead if you are there early in the month.

Packing for December

• Sunscreen, a hat and sunglasses. Long, bright days add up.
• A rain jacket, essential on the West Coast and in Fiordland.
• Warm layers for cool nights inland and in the mountains.
• Insect repellent for sandflies on the West Coast and in Fiordland.
• A sleeping bag rated for cold nights if you are camping in the Mackenzie or Central Otago.
• Swimwear. Beaches and lakes are at their busiest from Christmas.
