The double name Maunga Teatea and Pua Katiki possibly refers to how time here is broken apart (8½ * 29½ = 250¾).

Makoi arrives from northwest, on the side of the Day (Sun), and moves towards the side of Night (Moon). Thus the name Ehu (ashes etc) is appropriate for day number 240 (= ⅔ of 360), because the 'great fire in the sky' can be said to 'turn into ashes' with nightfall.

Ehu (cfr kehu and nehu)

Ehu ûa, drizzle.

Firebrand. Ehuehu: 1. Ashes. P Mgv.: ehu, ashes, dust; rehu, a cinder, ashes. Mq.: ehuahi, ashes. Ta.: rehu, ashes, soot, any powder. 2. Brown, brownish. P Ta.: ehuehu, red, reddish. Ha.: kehu, red or sandy haired. Mq.: kehu, fair, blond. Mgv.: keukeu-kura, id. Ma.: kehu, reddish brown. Sa.: 'efu, id. To.: kefu, yellowish. Fu.: kefu, blond, red. Niuē: kefu, a disrespectful term of address. Ragi ehuehu, a cloudflecked sky. 3. Imperceptible.

Pau.: kehu, flaxen-haired, blond. Ta.: ehu, reddish. Mq.: kehu, blond. Sa.: 'efu, reddish, brown. Mq.: kehukehu, twilight. Ha.: ehuehu, darkness arising from dust, fog, or vapor.

Once again the station has a double name, and we can compare with the kuhane stations:

24	*ko ehu ko mahatua a piki rangi a hakakihikihi mahina*
25	*ko maunga teatea a pua katiki.*

The eastern corner - 2nd part:
*14 Hanga Takaure*	*15 Poike*	*16 Pua Katiki*

The eastern corner - 3rd part:
*17 Maunga Teatea*	*18 Mahatua*	*19 Taharoa*

Makoi's order from west to east along the northern shore is opposite to that of the kuhane of Hau Maka, and we can therefore guess 24 Ehu corresponds to 19 Taharoa. When Sun is moving towards night he is going down (taha):

Taha

To lean; to go down (of the sun in the evening). Taha-taha. 1. Side, edge; shore: taha-taha tai. 2. To move from side to side (of a boat), to swing.

Moe tahae, to be a light sleeper. Tahatai (taha 1 - tai), littoral, coast, shore; tahatahatai, coast.

Earlier I have suggested that each station on Makoi's list is representing 10 days. If it is true, then also the kuhane stations could represent periods with 10 days in each. However, with Maunga Teatea and Pua Katiki mentioned together in the 25th item of Makoi each kuhane station maybe has only 5 days - 16 * 5 = 80 days up to and including 16 Pua Katiki and 8 * 5 = 40 days from 17 Maunga Teatea up to and including the birthplace of the new king at 24 Oromanga.

By the way, beyond 20 Hanga Ohiro there is a sign ko to be noticed, and it appears twice at what could be day number 240, presumably to indicate a break in time:

200	*hanga ohiro a pakipaki renga.*
210	*ko roto kahi a touo renga.*
220	*ko papa kahi a roro.*
230	*ko puna a tuki a hauhau renga*
240	*ko ehu ko mahatua a piki rangi a hakakihikihi mahina*
250	*ko maunga teatea a pua katiki.*
260	*ko te hakarava a hakanohonoho.*
270	*ko hanga nui a te papa tata ika.*
280	*ko tongariki a henga eha tunu kioe hakaputiti.ai*
	*ka haka punenenene henua mo opoopo o tau kioe*
290	*ko te rano a raraku.*

Whatever it means we should take the opportunity to map the occurrence of ko in Makoi's list:

There are 4 (page 38) + 12 (or 10) + 1 (page 40) + 1 (page 41) = 18 (or 16) blackmarked ko above. I guess ko could be a sign meant to signify the opposite of te, i.e. representing the back side.
