  • Navigator Jack Thatcher commanded the two waka hourua that sailed from Aotearoa (New Zealand) to Rapanui (Easter Island) and back. Te Aurere and its supporting vessel Ngahiraka Mai Tawhiti, known collectively as the Waka Tapu, set sail from Auckland on 17 August 2012.

    Waka Tapu

    The Waka Tapu refers to the voyage undertaken by Te Aurere and Ngahiraka Mai Tawhiti – waka hourua that sailed from Aotearoa to Rapanui and back. Both waka were built by Hekenukumai Busby. Navigation was without instruments.

    They sailed to Rapanui via Tubuai and Mangareva and then returned via Moorea and Rarotonga to arrive back in Doubtless Bay (in the Far North) 9 months later on 15 May 2013 – completing a journey of over 10,000 nautical miles (18,500 km).

    The crew of the two waka navigated without instruments. They used celestial navigation to guide them. They relied on the stars, Sun, Moon, ocean swells and currents, bird and sea life rather than modern technology such as GPS.

    The Polynesian triangle

    The goal of the journey was to close the Polynesian triangle. Some 3000 years ago, explorers, probably from South-East Asia, moved eastwards across the Pacific. Many settled in what is now known as Polynesia. These now diverse societies form the Polynesian triangle – with Hawaii in the north, Rapanui in the east and Aotearoa (New Zealand) in the south-west. The waka Te Aurere had already been to central Polynesia and north to Hawaii, but it was this voyage that completed the journey to the east – a journey many had suggested was an impossible task.

    The Polynesian triangle

    The Waka Tapu completed the last leg of the Polynesian triangle from Aotearoa to Rapanui and back in 2013. All three sides of the Polynesian triangle have now been navigated, linking Aotearoa, Hawaii and Rapanui.

    Confirming ancient voyaging

    The journeys confirm that it is possible to successfully and deliberately travel great distances (and in any direction) by canoe without using navigational instruments. Ancient Polynesians could have purposefully navigated in a similar way in double-hulled canoes to find new lands, including Aotearoa. It is believed that waka left Rarotonga over 800 years ago in search of Aotearoa. Most Māori iwi trace their origin back to these waka.

    Jack explains that going to Rapanui was quite a conquest. Although it is agreed that Māori ancestors brought kūmara back from the Americas, there are many theories about whether they navigated there and back intentionally. Most theorists believed the windward, eastern voyage towards the Americas was an impossible task, so Jack’s accomplishment helped to change people’s minds. Jack says,

    There are times seasonally when this journey can be done easily. We found a way, and this suggests that our ancestors knew this way also.


    The Polynesian societies all share a common origin. The goal of the Waka Tapu voyage was to reconnect with the people of Polynesia, and the culmination of this reconnection was to reach the east end – Rapanui. In the end, Jack and the crew found that the actual reconnecting with the people of Polynesia was the most important part of the journey. They spent hours sharing stories about common ancestors. They found that the various Polynesian cultures had a lot in common that went beyond similarities in language. Jack talks about a strong sense of belonging that made the voyage “a very right thing to do”.

    Navigator Jack Thatcher

    Jack Thatcher was chief navigator on the Waka Tapu voyage to Rapanui and back.

    Other research

    During the expedition, Jack made careful observations of celestial bodies, particularly the Sun. He is working to refine navigational strategies for keeping direction during the day when the Sun is not so reliable for that.

    The crew also collected research data for scientists. For instance, they collected information about ocean water temperatures for the Cawthron Institute.


    The journey was a collaboration between two New Zealand groups – New Zealand Māori Arts and Crafts Institute and Te Tai Tokerau Tarai Waka. The New Zealand Māori Arts and Crafts Institute in Rotorua focuses on guarding and teaching traditional Māori arts and crafts, and Te Tai Tokerau Tarai Waka teaches traditional sailing and navigation methods in Doubtless Bay in the Far North.
