The 'cut off' viri at Aa8-26 comes after the last glyph of Akahanga, and there seems to be a strong connection between not only Hua Reva and Akahanga but also including Hatinga Te Kohe:

Hua Reva 10 * 29.5 = 295
	Gb3-4	Gb3-5 (295)	Aa7-46	Aa7-47	Aa7-48	Aa7-49 (590)
Akahanga 11 * 29.5 = 324.5
	Gb4-4	Gb4-5 (325)	Aa8-20	Aa8-21 (647)	Aa8-22	Aa8-23 (649)
Hatinga Te Kohe 12 * 29.5 = 354
	Gb4-33	Gb5-1 (354)	Aa8-79	Aa8-80	Aa8-81	Aa8-82 (708)
Hanga Te Pau
	Gb5-11	Gb5-12	Ab1-16	Ab1-17	Ab1-18	Ab1-19

Hanga Te Pau is not one of the kuhane stations, and the lunar approximation of the solar year is calculated as 12 * 29.5 = 354. It ends with Hatinga Te Kohe.
