Labialized variant
Some languages, especially in Vanuatu, combine this labial–velar nasal with a labial–velar approximant release, hence.

In the Banks Islands languages which have it, the phoneme is written $⟨m̄⟩$ in local orthographies, using a macron on the corresponding bilabial. In other languages of Vanuatu further south (such as South Efate, or Lenakel), the same segment is spelled $⟨m̃⟩$ with a combining tilde.
