How to Get to Bollons Island #

Bollons Island is part of New Zealand’s remote Antipodes/subantarctic island groups and has no regular passenger service or airstrip. It can only be reached by sea as part of a private, scientific or expedition voyage departing from mainland New Zealand; landings (when permitted) are made by small boat/Zodiac from the visiting vessel. There are no roads or public transport on the island.

Tips for Visiting Bollons Island #

  • Access to Bollons Island is by sea as part of licensed expedition cruises or scientific visits only; plan through an operator that runs official landings and make arrangements well in advance of the austral summer season (December-March).
  • Expect strict biosecurity and landing controls-New Zealand's subantarctic islands are protected, and operators enforce cleaning and quarantine procedures, limited landing sites, and small-group landings to protect wildlife.
  • If you are on a cruise itinerary, listen to briefings from the expedition staff about where and when landings are permitted-wandering beyond designated routes is prohibited to protect breeding birds and fragile vegetation.

Best Time to Visit Bollons Island #

If attempting a visit, go in the austral summer (December-March) when sea and weather conditions are most favorable for expedition landings.

Austral summer (best)
December-March · around 5-10°C (subantarctic)
Relatively milder conditions and reduced sea ice make access by expedition vessels most feasible; wildlife activity and daylight are at their peak.
Shoulder season
November and April · around 0-8°C
Sea and weather conditions may still allow visits but are more changeable; shorter expedition windows and rougher seas are possible.
Austral winter (inaccessible)
May-October · around −2-5°C (colder seas and conditions)
Sea ice, storms and very rough seas generally make access impractical outside the summer expedition season.
