Maori loanwords are widely used in New Zealand English for various social
functions by New Zealanders within and outside of the Maori community.
Motivated by the lack of linguistic resources for studying how Maori loanwords
are used in social media, we present a new corpus of New Zealand English
tweets. We collected tweets containing selected Maori words that are likely to
be known by New Zealanders who do not speak Maori. Since over 30% of these
words turned out to be irrelevant, we manually annotated a sample of our tweets
into relevant and irrelevant categories. This data was used to train machine
learning models to automatically filter out irrelevant tweets.
