Formal:
* Te marena o tōku whaea me tōku papa: This translates literally to "the wedding of my mother and my father."
* Te marena a tōku whaea me tōku papa: This is similar to the previous one, but uses the possessive particle "a" instead of "o", which can be considered slightly more informal.
Informal:
* Te marena o ōku mātua: This translates to "the wedding of my parents."
* Te marena o tōku whānau: This means "the wedding of my family." This is a more general term that could encompass other family members besides just your parents.
Alternative:
* Te hui a tōku whānau: This translates to "the gathering of my family." It might be used if you want to emphasize the event as a family celebration rather than just a wedding.
The best option for you will depend on the context and the level of formality you want to achieve.
