I have focused on writing a play in the three languages of Aotearoa: New Zealand Sign Language, te reo Māori, and NZ English. Through the development of this script with three actors I have found techniques for performance and workshopping to encourage multilingual creative practice for a playwright. Through case studies of playwrights doing similar work at an international level, I have synthesised analytical and creative research into a final script and summary of my dramaturgical findings. Through creative practice in scriptwriting and developmental workshops, this research explores what story-telling modes, devices or styles seem particularly apt for conveying an inclusive and engaging trilingual narrative on stage. This specifically involves developing a dramaturgical set of insights for others who may want to do cross-language performance in Aotearoa.
