Tama is at 14 * 29.5 = 413, but tamaiti comes at 414:

Gb6-26 Gb6-27 Gb6-28 Gb7-1 Gb7-2 (413) Gb7-3 Gb7-4
Gb7-5 Gb7-6 Gb7-7 Gb7-8 Gb7-9 Gb7-10 Gb7-11
Gb7-12 Gb7-13 Gb7-14 Gb7-15 Gb7-16 Gb7-17 (428)

The kuhane station is not named Tamaiti, and we can guess the reason:

Gb6-26 Gb6-27 Gb6-28 Gb7-1 Gb7-2 Gb7-3 Gb7-4
Gb7-5 Gb7-6 Gb7-7 Gb7-8 Gb7-9 Gb7-10 Gb7-11

At winter solstice (Gb6-26) old sun has stopped and moves no more, he is 'dead'. Tamaiti at Gb7-3 is the new sun, but still only a child. I have blackmarked glyphs which seem to be associated with the old sun, and redmarked those denoting the son of old sun.

Moa in Gb7-1 is no real cock, the circumference of the glyph is not closed. Yet he is calling out the arrival of the child. In Gb6-27 another precursor of the new sun could be the curious sign emerging from henua (the mother). The sign at the top is drawn like a flame (tao).

In Gb6-28 tagata is at left and the same henua at right. Gb7-2 is the last glyph in the great lunar cycle, viz. number 413 - it cannot refer to the new year. Gb7-4 is a strange hau tea without any eye, light has vanished and it must refer to the old year.

Gb7-6 is a 'midnight henua', which means the new year has begun. Apparently Gb7-4 is the last glyph of the old year. No other 'midnight henua' can be found in the text of G.

Tama is not tamaiti, tama is the old sun, not the new sun child.

Ariki in Gb7-11 has the same sign at top left as tamaiti in Gb7-3:

7
Gb7-3 (414) Gb7-11 (422)
1 9

Possibly it means 'there is nothing at left' (this is the beginning). 58 + 422 = 480 = 24 * 60.

The glyphs which follow seem to refer to the moon:

Gb7-12 Gb7-13 Gb7-14 Gb7-15 (426) Gb7-16 Gb7-17 (428)

For once a fat mago comes first and a lean one in second place. The reason is that the fat one is pregnant. Hau tea at Gb7-14 is double-eyed (Janus). It is different from hau tea in Gb7-2 - it is not leaning - moon behaves in the same way irrespective of the sun season.

In Gb7-16 the same mago no longer is pregnant, she has given birth. Presumably the child is depicted in Gb7-15. Its ordinal number counted from tamaiti last year is 58 + 426 = 484, and possibly it is no coincidence that 48 * 4 = 192.
