Question 1

When is the best time to visit the Marlborough Sounds for scuba diving?

Accepted Answer

The easiest all-round window is January to April, when water is at its warmest and long daylight makes logistics simple. Local operators commonly quote water temperatures around {{ 13 | temperature }} to {{ 18 | temperature }} across the season, so most visitors are comfortable in a 7mm wetsuit or drysuit. May and November to December can be excellent shoulder months if you are flexible. Winter (June to August) can deliver quieter bays and sometimes clearer water, but cold exposure and wind systems make site selection more conservative.

Question 2

How do I get from Wellington to Picton for the Marlborough Sounds?

Accepted Answer

The most direct route is the Cook Strait ferry into Picton. Both Interislander and Bluebridge run sailings between Wellington and Picton, with crossings commonly taking about 3.5 hours. Once you arrive in Picton, you can walk into town, pick up a rental car, or meet a shuttle. If your accommodation is deeper in the Sounds or you are starting the Queen Charlotte Track, pre-book a water taxi from Picton. In summer and around public holidays, book ferries and water taxis early.

Question 3

Do I need an NZeTA or visa to visit New Zealand for the Marlborough Sounds?

Accepted Answer

Entry requirements depend on your passport. Many visitors from visa-waiver countries travel on a New Zealand Electronic Travel Authority (NZeTA), which is typically valid for 2 years and costs from NZD $17. If you need an NZeTA or certain visas, you may also pay the International Visitor Conservation and Tourism Levy (IVL), currently NZD $100. Apply early and allow up to 72 hours for NZeTA processing. Always verify your exact requirements and exemptions on Immigration New Zealand before booking non-refundable travel.

Question 4

How cold is the water in the Marlborough Sounds and what exposure protection should I pack?

Accepted Answer

Plan for cold-water exposure. A local Picton-area shop lists typical water temperatures around {{ 13 | temperature }} to {{ 18 | temperature }}, which can still feel chilly on a long second dive or a long snorkel. Many divers prefer a 7mm two-piece wetsuit with hood and gloves, while frequent visitors and technical divers often choose a drysuit for comfort. For snorkeling and freediving, a full 5mm to 7mm suit plus neoprene booties is a big upgrade. Pack windproof layers for boat rides.

Question 5

Can Open Water divers safely dive the MV Mikhail Lermontov wreck?

Accepted Answer

Yes, many Open Water divers can enjoy the Lermontov as an exterior wreck tour when conditions are calm and the operator is comfortable with your experience. The upper structure is in recreational depths, with reports placing the top around {{ 12 | distance:m }} to {{ 14 | distance:m }}. However, penetration turns it into an overhead environment and should be reserved for properly trained wreck divers with redundant gas, lights, reels, and strict team protocols. If in doubt, stay outside and enjoy the scale and fish life.

Question 6

Where are the best snorkeling spots near Picton in the Marlborough Sounds?

Accepted Answer

For easy access near town, start with Wiakawa's designated swim area to test your gear and tolerance for cold water. For a higher-impact day, Lochmara is a standout because it combines sheltered water time with an underwater observatory and a conservation-focused setting. If you can join a boat trip, Double Cove Marine Reserve is a popular sheltered option where fish can be very bold. Choose calm days for the best visibility and always use a snorkel float when outside marked swim zones.

Question 7

What are the key rules for visiting Long Island-Kokomohua Marine Reserve?

Accepted Answer

Treat the reserve as a strict no-take zone. DOC rules for Long Island-Kokomohua include no fishing, no collecting, and no feeding fish. Landing on Long Island is discouraged and only for emergencies without prior approval, so plan your day as a boat-based visit. Anchor carefully to avoid damaging the seabed, and be aware DOC warns of unmarked reefs, tidal changes, and strong currents around charted rocks. If you see illegal activity, report it through the appropriate hotlines listed by DOC and MPI.

Question 8

How do I plan a Marlborough Sounds trip for a mixed group of divers and non-divers?

Accepted Answer

Base in Picton if you want simple boat access and easy day trips, and add Blenheim as a day mission for wineries or museums. A common rhythm is: dive one day, do a Queen Charlotte Track section or cruise the next, then schedule another dive day when the weather window looks best. For multi-day hiking, budget for the required Queen Charlotte Track Land Cooperative pass on private-land sections and use water taxis plus luggage transfers to keep the group comfortable. Build at least one flexible day into the plan.

Question 9

Where is the nearest hyperbaric chamber and who do I call for a dive emergency?

Accepted Answer

For any immediate emergency, call 111. For diving incidents, call the Diver Emergency Service (DES) on 0800 4DES 111 (0800 4337 111) for expert advice and coordination. Hyperbaric treatment is not located in the Sounds itself. Christchurch operates a 24-hour acute hyperbaric service for New Zealand south of Taupo, and DES can coordinate referral and evacuation based on your location. Keep oxygen on dive boats when possible, maintain conservative profiles, and do not delay calling for help if symptoms appear.

Question 10

How do I safely and legally interact with dolphins, seals, and whales in the Marlborough Sounds?

Accepted Answer

Follow DOC marine mammal guidance and keep interactions passive. Do not chase or cut across the path of dolphins, and slow down early in areas where they are likely to surface. Give seals space on rocks and beaches and never position yourself between an animal and the water. Whales require extra caution, especially mothers with calves. If you are snorkeling or freediving, treat any close approach by wildlife as their choice, not an invitation to pursue. Operators in the Sounds will brief local rules and distances before wildlife cruises.
