The Hurricanes have been slammed for referring to an upcoming game against the Chiefs as the "Taranaki Land War".
Many took to social media to criticise the Hurricanes' social media post which has since been deleted.
Among those who spoke out against the post was former Maori Party co-leader Marama Fox, who called it "a sad indictment on our country's progression".
Fox said the incident is a sign of the country's ignorance of its own history.
"People are inadvertently making blunders like this because we don't teach it in our schools, so people don't understand how offensive it is," Fox told Newshub.
