I had thought that tere was a quite suitable word for the sunboat starting on its daily trip over the sky. Furthermore I had also considered the possibility that tere was a suitable description for these glyphs in the three parallel texts, also describing the second period when the sun is born (escapes from mother earth):

1. To run, to flee, to escape from a prison. 2. To sail a boat (also: hakatere); tere vaka, owner of a fishing boat. 3. (Deap-sea) fisherman; tere kahi, tuna fisherman; tere ho'ou, novice fisherman, one who goes deap-sea fishing for the first time. Penei te huru tûai; he-oho te tere ho'ou ki ruga ki te hakanonoga; ana ta'e rava'a, he-avai e te tahi tagata tere vaka i te îka ki a îa mo hakakoa, mo iri-hakaou ki te hakanonoga i te tahi raá. The ancient custom was like this: the novice fisherman would go to a hakanonoga; if he didn't catch anything, another fisherman would give him fishes to make him happy so he'd go again one day to the hakanonoga (more distant fishing zones where larger fishes are found). Vanaga.
