To qualify for the Blue Flag, a series of stringent environmental, educational, safety and accessibility criteria must be met and maintained.

The programme aims to connect the public with its surroundings and encouraging people to learn more about their environment. As such, environmental education activities must be offered and promoted in addition to a permanent display of information relevant to the site in terms of biodiversity, ecosystems and environmental phenomena.

OBC is one of three New Zealand marinas with Blue Flag accreditation – Westhaven and The Landing are the other two.
