Metoro may have been influenced by Aa6-70 when he said e he goe kua moe:
Aa6-66 Aa6-70
e he goe kua moe e mago

Metoro mostly said mago (shark) at the glyph type in Aa6-70, but of the 9 times he mentioned goe (Milky Way) it was mostly at the mago glyph type. I cannot have more than one label for each glyph type, but this is an instance where it would have been beneficial.

"Kepelino wrote: 'Lalani or stars of heaven are the stars close to the heavens, called ruling stars. There is a vast number of these stars and they shine with a tiny, twinkling light because of their great height.' Lalani, in the Kumulipo or Hawaiian Chant of Creation, was translated 'row of stars' by Queen Liliuokalani. The Hawaiians also called the Milky Way Kuamoo, Backbone of the Lizard.

Many Polynesian names for the Milky Way may be reminiscent of the crocodiles of Western Melanesia, the moko-roa, 'long lizards' of legend, for the same motif is found in various parts of the Pacific. The Tuamotuans termed the Milky Way Vaero-o-te-moko, Tail of the Lizard, and Mango-roa, Long Shark.

The Mangaian name Moko-roa-i-ata, Long-lizard-of-morning, not only sounds the lizard or crocodile note but also refers to the method of determining the small hours of the night before the rising of the morning star. The Maori used the same term contracted to Mokoroiata. Again they called the Galaxy Mango-roa, Long Shark, and Mangoroiata, Long-shark-of-dawn.

In the island of Pukapuka Te Mango, the Shark, was applied to the long dark rift which divides the Milky Way from Scorpius to Cygnus. They declared that the 'shark of winter' had its head to the south and the 'shark of summer' had its head to the north, referring to the seasonal change in the position of the constellation.

This, they said, was the monster which Maui speared and hurled high into the sky and they pointed out a small triangular patch of dark nebulosity near Scorpius as te tao, the spear with which Maui had performed his prodigious feat. In the Society Islands there were two distinct names for the rift, Vero-nu'u, Pierce-the-earth, and Vero-ra'i, Pierce-the-sky, the names of the two great wooden spears of Tane.

The Central Polynesians called the Milky Way the Vai-ora or Water of Life of Tane and located it in the tenth heaven. They tell the story of Faa-rava-i-te-ra'i, Sky-shade, a handsome blue shark which was the pet of the gods. Unfortunately, it developed an appetite for human beings and two lads plotted to kill it, but the gods learned of their purpose in time and transported the shark to the heavens where it can still be seen. When Maui ascended to the tenth sky to implore the assistance of Sky-builder, he found the god diving for fish in the Living Water to feed his pet sea swallow, the star Deneb in Cygnus ... (Makemson)

It may be that the 'long lizards' of Melanesia have nothing to do with the origin of the Polynesian names for the Milky Way. The origin may instead lie in Maia-wa (the distant land of Maya). I cite from Maya Cosmos:

"... Yucatan crosses today are ... referred to as yax che', 'First (or green) Tree'. Yax che' also happens to be the name of the ceiba tree, and we have naturalistic images from the Classic period of fruit-laden ceibas that represent the World Tree ..."

"... The form they gave to the Raised-up-Sky and the central axis of the world was that of a great ceiba tree. That tree is still there as the cross and as the tree ..."

"World trees are a prevalent motif occurring in the mythical cosmologies, creation accounts, and iconographies of the pre-Columbian cultures of Mesoamerica. World trees embodied the four cardinal directions, which also serve to represent the four-fold nature of a central world tree, a symbolic axis mundi which connects the planes of the Underworld and the sky with that of the terrestrial realm ...

Among the Maya, the central world tree was conceived as or represented by a ceiba tree, and is known variously as a wacah chan or yax imix che, depending on the Mayan language. The trunk of the tree could also be represented by an upright caiman, whose skin evokes the tree's spiny trunk ...

World trees are frequently depicted with birds in their branches, and their roots extending into earth or water (sometimes atop a 'water-monster', symbolic of the underworld). The central world tree has also been interpreted as a representation of the band of the Milky Way." (Wikipedia)

"As the Milky Way turns from its north-south position as World Tree to its east-west position as the Cosmic Monster, it arches from the southwest to northeast quadrants of the sky. At that time it looks as if the crocodile is riding just above the swollen bulge of its base.

This 'crocodile tree' is a very ancient image among the Maya and is featured in Popol Vuh version of Creation. In fact, a monument from the very early ceremonial center of Izapa in Chiapas shows this crocodile tree along with a picture of one of the Hero Twins after his arm has been ripped off in a struggle with Itzam-Yeh, the Classic name for Seven-Macaw. With his good arm he is holding a pole on which a Late Preclassic-period version of Itzam-Yeh perches.

If Itzam-Yeh was symbolized by the Big Dipper in the Classic period, this picture also happens in the sky. When the Wakah-Chan Milky Way moves from its erect north-south position and becomes the Crocodile Tree, the Big Dipper dives downward until it touches the horizon. It disappears as the Crocodile Tree changes into its east-west Cosmic Monster. I believe this movement may correspond to the defeat of Seven-Macaw by the Hero Twins."
