The following information has come from the APA manual (2019, pp.260-261).
Traditional Knowledge is referenced based on how the information was recorded.
If the information being referenced has been recorded, it should be referenced according to the APA style for that source (e.g. book, article).
However, you can choose to acknowledge the author as an Elder, where applicable, and Nation Group (if known) further in your text.
If the author's name includes Elder, Aunty, or Uncle in the byline of the publication, treat this as an inseparable multipart name and preserve their full name in the reference list.
Follow the format for the reference type in which the interview was published. When the person being interviewed doesn't appear in the author element in the Reference, integrate their Nation Group, title if applicable, and full name into the narrative of the sentence.
If the information you are citing has not been recorded in a way that it can be recovered by a reader it should be cited as personal communication. This includes email, text message, online chat, direct message, personal interview, telephone conversation, live speech, unrecorded classroom lecture, memo, or letter, etc.
