That prompted William Walker, the director of the hugely popular and successful Waiora play, to contact Mr Brash.
Mr Walker contacted Mr Brash and invited him to attend Waiora in the hope that he might find the answer to his question in the performance and Mr Brash has taken up the challenge and confirmed that he will be attending at 7pm tomorrow night.
''I recommend that anybody who has an issue with the prevalence of Maori words on government buildings and documents and on public radio and television, come to the show.'' Mr Walker said.
''Waiora is a totally engaging show that vividly illustrates the issues Maori faced when they were adapting to the new industrial/capitalist lifestyle the Pakeha brought with them to New Zealand. If we understand that, we understand the importance of inclusion of Maori culture in mainstream New Zealand today. Good on Don for taking up the challenge."
Whangarei Girls' High School has added two extra dates to their graduation production Waiora. The play, written by Hone Kouka, was first performed by the school in May but due to high demand it was brought back. It is the first time one of the school's Year 13 graduation productions has returned for a second season.
The last show was expected to be Sunday but because of popularity the school has added two more shows tomorrow and Friday at 7pm.
