Here are some other ways to express gratitude in Tahitian:
* Mauruuru roa - Thank you very much
* Mauruuru maitai - Thank you so much
* Mauruuru no teie - Thank you for this
* Mauruuru no tau tauturu - Thank you for your help
Remember that Tahitian is a tonal language, so the pronunciation of "Mauruuru" is important. The stress should be on the first syllable, with a slight rising intonation on the "u" sound.
