"DOC and island staff on other islands in the gulf are considered one bubble and to keep them safe we are asking people to not venture to the islands," she said.
As the weather improves, DoC also urges people to brush up on their marine reserve rules before hitting the beach, boat or sea.
Are you familiar with some of DoC's key marine rules?
Do not collect shellfish or disturb any marine life.
Do not feed fish.
Do not take any part of the seafloor, including rocks and shells.
Do not discharge any waste, sewage or litter.
Check your boat and gear for stowaway pests
No dogs on pest-free islands or DOC reserves.
DOC marine rangers also patrol popular areas to ensure rules are being followed. So, if you need some additional information about an activity or destination, check out the DoC website.
Those who notice any offences are asked to report them by calling 0800 DOC HOT.
