Perched high above the rugged cliffs of Muriwai, we find ourselves at the Gannet colony. This spot offers an unparalleled view of one of New Zealand’s most accessible mainland gannet nesting sites. The Gannet colony here is a must-see for anyone visiting Auckland.
From August to March, these majestic birds occupy the rocks and cliffs. They prepare nesting areas, breed, hatch, and raise their chicks. It is truly a spectacle of nature. Muriwai’s Gannet colony is one of only three mainland nesting sites in New Zealand. The other two are Cape Kidnappers and Farewell Spit. Muriwai stands out as the most easily reached location.
The Gannet colony was established early in the 20th century on Oaia Island. Overcrowding led the gannets to Muriwai in 1975. They first nested on Motutara Island. By 1979, they spread to Otakamiro Point on the mainland.
The Auckland Regional Council established the Takapu Refuge in 1979. They worked with the Royal Forest and Bird Protection Society. This ensured the gannets had a protected space to thrive. In 1995, a sudden drop in gannet numbers caused concern. The population mysteriously fell from 1400 to 226 in just six weeks. However, the gannets returned shortly after. They have expanded their nesting sites on the mainland since then.
These gannets, known as Australasian gannets or Takapu, are impressive birds. Their wingspan can reach up to 180 cm. Their overall length is about 90 cm. They typically lay a single egg around September, October, or November. The incubation period lasts about 44 days. Chicks stay in the colony until February or March. After that, the birds migrate to Australia. They return after 2 to 6 years.
Viewing the Gannet colony is an amazing experience. The best viewing conditions are on a breezy day. The birds fly higher, often level with the viewing platforms. Windy conditions also seem to increase their activity. Remember to bring binoculars for a closer look. Photographers should visit in the morning or late afternoon for better lighting.
Don’t forget to look down into the water. You might spot Maui’s dolphins or New Zealand fur seals. Gannets can also be seen skimming the waves or diving for food. Keep an eye out for gannets diving at high speed from up to 30 meters. It’s a truly spectacular sight.
Before you leave the Gannet colony, take a moment to appreciate the unique landscape. Muriwai’s black sand is a magnetic iron mineral. It comes from volcanoes in the central North Island. The Waikato River carries it to the Tasman Sea. Sea currents then wash it up onto the beach.
The Maukatia Gannet Track provides easy access to the viewing platforms. From the car park, follow the signs to Maori Bay. The track leads through a short section of bush. It also includes two spectacular lookout points. You can enjoy panoramic views of Maori Bay, Muriwai Beach, and Woodhill Forest.
Remember, dogs are not permitted on the track. This helps protect the gannets and their habitat. The track may temporarily close for repair work after the gannets leave in March or April. Always check the track status before you visit. A visit to the Gannet colony offers a unique chance to connect with nature. It allows us to witness the beauty and resilience of these amazing seabirds.
