Miriana Kahu was the third, albeit temporary, commanding officer of the USS Cantabrian (NCC-24705) in 2341 after the disappearance of Captain Jack Annand in the same year. She was a Māori New Zealander. (Star Trek: The Cantabrian Expeditions)

We assume Miriana Kahu was Jack Annand's first officer and stepped in as commanding officer until a replacement could be found. It's not known if she remained on as first officer or accepted a command of her own after her stint as the Cantabrian's acting captain.'
