Getting there is easy: It's just a forty minutes drive from Auckland to Muriwai. From the car park leads a short walking track to the main gannet colony and a viewing platform.

The popular Muriwai Beach is patrolled during summer. Swimming between the flags is allowed
The summer is the peak season. From December to March weekends are more crowded due to beach visitors and surfers. There is limited parking! Therefore, visit the colony either early in the morning or late afternoon if you visit on weekends. Mid-week and spring are less busy. It's also usually more crowded on sunny days. On the other hand, there are very few visitors during cold, rough days.
Warmest months are in the summer from December until March often with pleasant temperatures around 20 °C at daytime and 10-12°C in the night. The coldest months are in the winter from June to August, but it's not freezing. Most precipitation occurs in winter but it already starts in May with its peak in July. Driest months are during the summer from November to February/March. The best months for swimming at Muriwai Beach are January until March, but the sea temperature is still lower than 20 °C.
Tip: Be prepared for the windswept coastline and bring a warm jacket. If you are downwind, you experience the penetrating smell of gannet poo.
The gannets are common to New Zealand. Most of the gannetries occur on the Northern Island with the biggest colony on Cape Kidnappers. Check more photos from the Muriwai Gannet Colony on flickr: Muriwai Gannets - Photo Stream
Facts about the Australasian Gannets and the Nesting Season
- Gannets often live in large colonies on cliffs, islands and coastal rocks completely or almost surrounded by the sea.
- The male birds return first to their nest. The mutual bill fencing between the gannet pairs is an impressive greeting ceremony.
- They may remain together for several years, some mate for life.
- Each gannet pair has one egg. If the egg gets lost or broken within the first weeks, a gannet can lay a second egg.
- The incubation of the egg lasts more than 40 days.
- The chicks hatch naked and blind. After one week they are already covered with fluffy down.
- One of the parents is always guarding the nest while the other is hunting for fish.
- The juveniles leave the nest roughly after 100 days and migrate to Australia. They return to their home colony after 3 to 5 years.
- The gannet lifespan is extremely long with more than 25 years.
- They weigh nearly 2.5 kg and have a length of almost 90 cm.
It is a very rare opportunity to watch the blue-eyed gannets close. You may also spot seals, dolphins or even penguins in the sea. There isn't any entrance fee requested.
