"Arohanui ki a koutou katoa"
This translates to:
* Arohanui: This is the most common and widely used word for "love," but it also implies a strong sense of affection and care.
* ki a: This is the preposition "to" or "for."
* koutou: This is the plural form of "you," referring to multiple people.
* katoa: This means "all" or "everyone."
You can also use:
"Nga mihi nui ki a koutou katoa"
This means "Many thanks to you all" which, in this context, implies a sense of missing someone and wanting to express gratitude for their presence.
Both phrases are appropriate ways to express that you miss everyone.
