The Maori word for bye is "haere rā" or "ka kite."
Haere ra means goodbye when said to someone who is leaving.
"Te amo haere" is not a common phrase in any language that I am aware of. "Te amo" means "I love you" in Spanish and "haere" means "go" in Maori. It could be a combination of words from different languages with no specific meaning.
It means farewell (said to someone who is leaving).
In Maori, "haere mai" means "welcome" or "come here." It is often used as a greeting to invite someone to come closer or to indicate that they are welcome.
haere mai means:(interjection) come here! welcome! - a greeting
In Maori, you can say "Haere pai atu, haere pai mai" which means 'Have a safe journey'.
In Maori, "Go away" is "Haere atu."
Kia pai te haere. Kia pai hoki te haere mai. Ko tēnā.
I think the closest would be 'Kia pai te haere' ...
Haere Ra(farewell).
Haere maru, haere papu (go slow, go sure)
