Ana-heu-heu-po is number 5, which ought to mean 'fire' (rima):

5

Ana-heu-heu-po, the pillar where debates were held

Alphard, α Hydrae

-08° 26'  09h 25

At 09h 25 Alphard lies about 4 hours (or 4 / 24 * 12 = 2 months) earlier than Spica:

3

Ana-roto, middle pillar

Spica, α Virginis

-10° 54'  13h 23

3 for Spica and 5 for Alphard could refer to '3-fingered spring' respectively to 'winter solstice' (when a new fire must be lit).

According to the 2nd list of place names item 13 (10 more than 3) is at Cabo Norte, which could correspond to Spica. If so, then Alphard should come earlier and on the western coast.

If the new 'fire' at Alphard will be finished after a duration of 10, then item 4 in the list could correspond to Alphard because item 13 (at Cabo Norte) apparently indicates where this 'fire' no longer lives (no longer can be seen):

4 Okahu a uka ui hetuu.

5 ra tahai a uo.

2
6 ahu akapu a mata kurakura.

7
11 roro hau a mana ai rea.

8
12 vai poko aa raa mata turu

9
13 ko te hereke a kino ariki

A capital letter for Okahu apparently means that a new season is beginning with item 4. Vai at item 12 could mean that in the 9th period counted from Okahu the 'fire' is 'liquidated'. Another vai in the 6th period indicates there are 2 such events, i.e. that the western coast should have as its topic Moon (and not Spring Sun who has only one 'wing'). Measuring the year by Moon could implicate ⅔ for spring (or summer) and ⅓ for autumn (or winter):

13 * 29.5 = 383½ is at Roto Iri Are which agrees with Ana-roto, when Sun is also said to be 'inside' (roto). Down in 'the Underworld' - inside the earth - the prow of the Sun 'canoe' carries a 'sea' swallow (manu tara) as a pilot, a bird which like the prow of Argo 'can speak and render prophecies' and which is capable of leading the way out in early spring.

Maybe 4 * 29.5 = 118 could be the time when Sun returns out in the open:

17
Ga5-4 Ga5-5 Ga5-6 Ga5-7 (118) Ga5-8 Ga5-9

118 + 64 = 182 which could mean the 'Underworld' corresponds to the winter half of the year.
