Goodbye:
* Kia ora! (General greeting, also used for goodbye)
* Arohanui! (With love)
* Ka kite! (See you later)
* Haere ra! (Go well!)
* Tena koe! (Goodbye, respectful)
Good luck:
* Kia kaha! (Be strong!)
* Mauru ora! (Good health!)
* He pai te wa! (Have a good time!)
* Manaakitanga! (Blessings/May you be well-cared for)
You can combine these phrases to create a more complete farewell:
* Kia ora, haere ra, kia kaha! (Goodbye, go well, be strong!)
* Arohanui, mauru ora, he pai te wa! (With love, good health, have a good time!)
It's always good to consider the context and your relationship with the person you are saying goodbye to. A simple "kia ora" might be appropriate for a casual encounter, while "aroha nui" is more suitable for a close friend or family member.
