I decided to aggregate these 3 periods by cause of the eating gesture (kai). Only later did I realize they should belong together also because of their period numbers, which can be correlated with kuhane stations. By eliminating Te Pu Mahore and Te Poko Uri from what should be counted Mercury will be at the birthplace Oromanga and Saturn at the residence for the abdicated king, and the whole island will be number 26:

Te Pu Mahore

Te Poko Uri

1	*Te Manavai*	8	*Hatinga Te Kohe*	15	*Maunga Teatea*
2	*Te Kioe Uri*	9	*Roto Iri Are*	16	*Mahatua*
3	*Te Piringa Aniva*	10	**Tama ()***	17	*Taharoa*
4	*Te Pei*	11	*One Tea (†)*	18	*Hanga Hoonu*
5	*Te Pou*	12	*Hanga Takaure*	19	*Rangi Meamea*
6	*Hua Reva*	13	*Poike*	20	*Peke Tau O Hiti*
7	*Akahanga (†)*	14	*Pua Katiki*	21	*Maunga Hau Epa*

22	*Oromanga*	23	*Hanga Moria One*	24	*Papa O Pea*	25	*Ahu Akapu*
*birthplace of the new king*		*residence of the current king*		*residence for the future king*		*residence for the abdicated king*
*26 Te Pito O Te Kainga*

This makes better sense than my earlier colours. And we can put Ahu Akapu together with period number 25 (the first glyph of which has an empty-handed hanau with 4 hanging maro feathers):

25
25	*Ga6-17 (18)**	Ga6-18 (159)

Possibly the whole island corresponds to period number 26:

26
26	Ga6-19	Ga6-20 (161)

The henua design in Ga6-20 is different, with straight ends instead of the otherwise curved standard for henua signs in the G text. But we should notice a straight bottom end also in period 22.

It would be to expect too much if we thought we could correlate all kuhane stations with all henua periods, but period number 18 - we must notice - has honu glyphs:

*18 Hanga Hoonu (?)*

Ga5-10	Ga5-11	Ga5-12	Ga5-13 (124)	Ga5-14	Ga5-15	Ga5-16

And the following 19th period is beginning with a kind of vero - i.e. ragi without any crescent indicating light. Its 5 glyphs could therefore correspond to the 5 nights beyond 18 * 20 = 360:

*19 Rangi Meamea (?)*

Ga5-17	Ga5-18	Ga5-19 (130)	Ga5-20	Ga5-21
