Here are some options:
For "leave me alone":
* Tuku ahau: This is the most literal translation, meaning "leave me" or "let me be."
* Whakarerea ahau: This means "leave me alone" and has a stronger emphasis on being left undisturbed.
* Hoki atu koe: This means "go away," and can be used if you want someone to leave you completely.
For "leave me (behind)":
* Waiho ahau: This means "leave me," but implies that you are being left behind in some way.
* Ka waiho ahau e koe: This translates to "you will leave me."
For "leave me (in a place)":
* Waiho ahau ki konei: This means "leave me here."
* Whakatū ahau ki konei: This means "leave me standing here."
It's always best to consider the context of the situation and choose the most appropriate phrase.
For example, if you are asking someone to stop bothering you, "Whakarerea ahau" would be a good choice. But if you are simply telling someone you are staying behind, "Waiho ahau" might be more appropriate.
