1 RAINBOW WARRIOR

This Greenpeace ship was sabotaged and sunk by the French government in Auckland’s Waitematā Harbour in 1985. The ship was later moved to become an artificial reef near the Cavalli Islands, where divers now explore a huge variety of marine life in about 85 feet of water.

2 MILFORD SOUND

Not all those who wander are lost, so make sure not to miss New Zealand’s most famous “tramp,” as the Kiwis refer to hikes. The roughly 33-mile route takes about four days (you can sleep in huts or camp along the way), and features glacier-carved fjords and valleys as well as the country’s tallest waterfall.

3 POOR KNIGHTS ISLANDS

Home to the world’s largest sea cave and often called “Middle Earth in the middle of the ocean,” this marine reserve about 14 miles off the North Island’s Tutukaka Coast has clouds of schooling pink maomao (a type of sea bass), moray eels, thick kelp forests and colorful anemones.

4 SEA KAYAKING AND WINE TASTING

Marlborough Sounds is the sunniest spot in New Zealand (which is so green for a reason), and a stunning place for sea kayaking adventures. On land, don’t miss tastings at the vineyards producing the country’s celebrated sauvignon blanc.

5 MIKHAIL LERMONTOV

Stretching over 570 feet long, this former Soviet cruise ship met its demise in the Marlborough Sounds in 1986 after hitting rocks on a shallow reef. A 2017 earthquake rearranged the wreck, giving divers more nonpenetration access into the intact skeleton in 125 feet of water.

6 FIORDLAND

New Zealand’s most dramatic mountain-meets-ocean landscapes are found on the South Island in Fiordland, famous for Milford Sound. Explore the sheer underwater cliff faces home to the world’s largest concentration of black corals (they’re actually white).

7 HMNZS CANTERBURY

Upright and intact off the North Island’s rugged Cape Brett Peninsula, this former navy frigate beckons wreck fanatics. Recreational divers can explore the upper deck and bridge, where a swim-through leads to the helicopter hangar. And advanced divers can fin down to the lower levels and stern at roughly 120 feet.

8 TONGARIRO ALPINE CROSSING

The North Island is home to the country’s most spectacular day hike, 12 miles through volcanic terrain that’s best undertaken during summer months. Old lava flows, jewel-hued lakes and steam vents are among the sights.

9 ARAMOANA MOLE WRECKS

Seahorses, sevengill sharks, sea lions, carpet sharks and nudibranchs are among the creatures big and small that live on a cluster of scuttled wrecks surrounded by kelp forests off Dunedin.

10 WHALE WATCHING IN KAIKOURA

Operators boast a 95 percent success rate of seeing sperm whales offshore year-round at Kaikoura, on the South Island, the country’s most popular spot for seeing cetaceans. From June to August, migrating humpbacks are often spotted here too.
