Oamaru has built a 25 metre tunnel to help their local penguins pass the busy road between the sea and their nests.
Penguins in the town are rare ‘blue’ penguins, the smallest kind in the world, and are an endangered species.
Before the underpass, the birds crossed the road protected only by a “penguin crossing” sign.
The underpass was started in September this year, and was opener earlier this month.
Oamaru’s blue penguin colony is one of the few populations in the world that is actually growing.
