Astronomy
Mātāmua's career in traditional Māori astronomy began in 1995 when, as a university undergraduate, he asked his grandfather Jim Moses (Timi Rāwiri Mātāmua) about
Matariki, the Māori New Year heralded by the rising of the
Pleiades
The Pleiades (), also known as Seven Sisters and Messier 45 (M45), is an Asterism (astronomy), asterism of an open cluster, open star cluster containing young Stellar classification#Class B, B-type stars in the northwest of the constellation Tau ...
at dawn. Timi Rāwiri produced from a cupboard a 400-page manuscript written in Te Reo Māori. The manuscript had been written over many years in the 19th century by Timi Rāwiri's grandfather Rāwiri Te Kōkau and father Te Kōkau Himiona Te Pikikōtuku, who was a
tohunga of
Tūhoe and
Ngāti Pikiao.
It was an astronomical record containing the names of 1000 stars and 103 constellations, as well as instructions for setting up a traditional house of astronomical learning or whare kōkōrangi.
Timi Rāwiri told Mātāmua to share the knowledge it contained: "Knowledge hidden, he said, wasn't knowledge at all."
Mātāmua has since written widely on Matariki, identifying the nine stars that Māori perceived in the cluster, in contrast to the seven associated with the Pleiades in European tradition. His research has revealed that some of the Māori astronomical lore recorded by ethnographer
Elsdon Best is slated or incorrectly translated. The translation of the word Matariki to mean "little eyes" is one such error; the name in fact is derived from ''Ngā mata o te ariki o Tāwhirimātea'', the eyes of
Tāwhirimātea, god of the winds.
He has pointed out that the Matariki is often celebrated too early, when it is still below the horizon, as a result of a mismatch between the
Gregorian solar calendar and the Māori lunar/stellar calendar, where the dates for Matariki change every year.
Mātāmua has been critical of the way Western scientific astronomy has ignored or belittled traditional Māori knowledge.
He intends to establish a Māori observatory, based on a traditional observatory but incorporating modern knowledge and technology.
Mātāmua chairs the Matariki Advisory Group which has provided advice to the Government on the formation of New Zealand's newest public holiday,
Matariki, which was first celebrated on Friday 24 June 2022. In October 2022 he was appointed to the newly-created position as chief advisor to the Government on Matariki.
Science communication
Mātāmua regularly posts videos and podcasts on Māori astronomy in both English and
Te Reo Māori, and has a large social media following: his ''Living by the Stars'' Facebook posts have over 20,000 followers, and his web series accumulated over one million views in four months.
In 2019 he gave 21 presentations to a total audience of over 10,000 in New Zealand and Australia.
Honours and awards

On 30 June 2020 Mātāmua was awarded the 2019
Prime Minister's Science Communication Prize for his work writing and speaking about Māori astronomy and Matariki. He is the first Māori scientist to be awarded the prize. He also won the 2020
Callaghan Medal for his work engaging the public at the boundary between science and traditional Māori knowledge. In March 2021, Mātāmua was awarded Fellowship of the Royal Society Te Apārangi, in recognition that his work "has revolutionised understandings of Māori astronomy, and in particular Matariki".
In the
2023 New Year Honours, Mātāmua was appointed an
Officer of the New Zealand Order of Merit, for services to Māori astronomy.
Mātāmua was named New Zealander of the Year in the 2023 Kiwibank New Zealander of the Year awards.
In December 2023, he received an honorary doctorate of literature from Te Herenga Waka—Victoria University of Wellington.
