Dive Site Overview
The MS Mikhail Lermontov, a formidable Russian cruise liner that sank in 1986, lies on its starboard side in Port Gore. This immense wreck, measuring 155-176 meters / 508-578 feet in length, presents an impressive underwater landscape.
Open water divers can explore its shallowest sections, observing the exterior hull and the impact of marine growth over decades. For those with advanced wreck penetration training, the deeper parts offer access to various internal areas like the ballroom and The Nevsky Bar. Navigation inside can be complex, so proper training and planning are essential.
The wreck environment is often silty, necessitating excellent buoyancy control to maintain visibility. A navigational marker buoy is present; however, divers should avoid using it for mooring.
Protected as a voluntary no-take area, the wreck fosters a thriving marine ecosystem, adding to the dive's appeal. Its sheer scale and the history behind its demise contribute to a profound diving experience.
Best Time to Dive
Optimal diving at the MS Mikhail Lermontov Wreck typically aligns with New Zealand's warmer months, offering air temperatures that enhance the overall experience. January, February, and March generally show strong dive scores, with average air temperatures ranging from 15.6-17.2°C / 60-63°F, and minimal rainfall around 1.5-2.1 mm. Wave heights are often manageable, usually under 0.72 meters. Conversely, cooler air temperatures prevail during winter, with July dropping to an average of 10.3°C / 50°F. Despite this, August can still present good diving opportunities, with air temperatures averaging 9.9°C / 50°F, indicating that conditions aren't solely dictated by warmth. Wind speeds vary, sometimes reaching over 30 km/h / 18 mph, particularly in spring. Due to the wreck’s exposure to Cook Strait, conditions can fluctuate; checking real-time weather and sea state predictions before any dive is always recommended.

Dive Experience & Conditions
Accessing the MS Mikhail Lermontov typically requires boat diving experience, as the site is exposed to the varied conditions of Cook Strait. Upon entry, divers encounter a large wreck lying on its starboard side, extending from its shallowest points down to its deepest sections. This depth profile makes it accessible for open water divers to explore the outer hull. For those with advanced training, particularly in wreck penetration, the deeper interior spaces offer extensive exploration. Buoyancy control is paramount here; the wreck is notably silty, and disturbing the sediment can drastically reduce visibility for everyone. Utilizing Nitrox is highly recommended for advanced divers to extend bottom time safely given the depth profile. Conditions can vary, with currents sometimes present depending on tidal movements and weather patterns.
Dive Difficulty & Safety Guidelines
Exceptional buoyancy control is paramount when exploring the MS Mikhail Lermontov Wreck. Silt inside and around the vessel poses a significant hazard; disturbing this sediment can quickly obscure visibility, making exit and navigation extremely challenging within the wreck's interior. Proper finning techniques are essential to prevent this. Due to its exposure to Cook Strait, expect variable currents and sea conditions, requiring prior boat diving experience. Wreck penetration should only be attempted by divers with appropriate technical training and certification, as the ship's intricate layout and potential entanglement hazards demand advanced skills and specialized equipment. For site preservation, divers must not use the navigational marker buoy for mooring, and the entire area operates as a voluntary no-take zone to protect marine life.
