The first light, the sacred star — one of the stars who guided the priests and chiefs in their discussions and undertakings. Ao-tahi (Canopus) was a child of Puanga (Rigel); his mother's name was Taku-rua (Sirius).
The following are four versions of names for the star Canopus:
- Ao-tahi: Ao, cloud, dawn, day; tahi, one.
- Au-tahi: Au, stream, current, ripple; tahi, one.
- A-tu-tahi: A, is; tu, stand; tahi, one.
- Tu-tahi: Tu, stand; tahi, one.
Aotahi he whetu tapu, he ariki aia no nga whetu o te tau, and, Tera Atutahi ka mahuta i te pae.
