The Sounds Retreat, Marlborough
This exclusive one-suite retreat opened in the easternmost arm of the Marlborough Sounds in July. Owned by Anne and Tony Brooker, it has an outdoor hot tub, fully equipped gym and private live-in chef. All of New Zealand's landscapes are here: there's hiking in the forest behind, dolphins darting in the waters in front, wine-tasting in Blenheim and whale-watching offshore at Nelson. Guests are free to explore the area using mountain bikes and a convertible Mini Cooper S.

This white cube-shaped lodge stands amid the dunes of the Kapiti Coast. Each of the four suites is named after indigenous plants that grow in the immediate area, with Maori furnishings and outdoor patios that have views of the Tasman Sea. Spend days relaxing beside the pool, strolling along Peka Peka beach or exploring the nature reserve on Kapiti Island, which is home to exotic birdlife such as the flightless takahe and diminutive little penguin.

Otahuna, Tai Tapu
This century-old residence was built for the prominent politician and lawyer Sir Heaton Rhodes. It's now a listed country house hotel that's set in rural splendour outside Christchurch. There are rolling lawns in front and a range of palatial suites with open fireplaces, wood-panelled walls, oak furniture and classic houndstooth fabrics. Memorabilia that nods to Sir Heaton's favourite pastimes – polo clubs, stag horns and botanical prints – add a sense of history.

A romantic retreat for those with the environment at heart. This off-grid B&B opened above a scenic swathe of Hokianga Harbour a year ago. Powered by solar panels, it offers just one luxury treehouse-style suite, with a pre-stocked fridge that's filled with organic and fair trade products. Guests are treated to a two-course breakfast on the sweeping balcony each morning, with scrambled eggs, smoked salmon and free-farmed bacon all on the menu.

Tin Tub, Wanaka
Tin Tub opened above the waters of Lake Wanaka in July. Run by Trish (who cooks the breakfast) and Barry (who handles the excursions), it has upmarket suites with Jacuzzi baths and outdoor patios, and some simpler rooms with balconies and views of the jagged peaks.

The Oyster Inn, Waiheke
Andrew Glenn worked as a marketing director for Topshop before leaving London with his partner in 2011. Craving a lifestyle where they could "put their feet on the sand every day", they opened Oyster Inn on Waiheke Island in November. Located on Oneroa Beach, it has the feel of a clapboard summer cabin, albeit with a cocktail bar, seafood restaurant and three whitewashed rooms. A vintage Volkswagen camper-van is on hand for excursions.
