Rugby fans keen to see a bit more of Dunedin than Otago Stadium are being encouraged to take tours rather than go exploring by themselves.
The Department of Conservation is keen for people to take tours to maximise their wildlife experience on Otago Peninsula.
Biodiversity assets programme manager David Agnew said to accommodate the influx of visitors, Doc was allowing the Royal Albatross Centre at Taiaroa Head to open for an extra week.
"We've assessed the disturbance risk to the colony and decided it is low this year so have agreed to the extension."
It meant the centre could open until September 25.
However, some other Doc reserves were closed because of lambing on adjacent properties including Tunnel Beach, Sandymount and Hayward Point.
For those who did go investigating by themselves, they needed to keep their distance, at least 10m, from wildlife such as sea lions, fur seals and leopard seals. If penguins saw people, that was close enough to disturb them, he said.
"There is good signage and information at the reserves and beaches and people need to take notice and read the information."
People also need to take note of the travel times on the peninsula and give themselves plenty of time to get back to town.
"They are narrow winding roads along the peninsula so people need to take care."
