The Maori Council is prepared to take the Government to court over another matter.
None of the spectrum the Government is auctioning off later this year will be reserved exclusively for Maori, because the Government doesn't believe Maori need more radio airwaves to protect their language and culture.
Maori Party co-chair, Maanu Paul, says just like over water rights, the Government isn't talking to Maori.
He says that's what's led them to court, and they'll go again over this issue.
Mr Paul says the spectrum is taonga, therefore Maori are entitled to it under the Treaty of Waitangi.
"It's a brutal way of the Government to treat its Treaty partner and I think the whole of New Zealand should know that this Government is a Government with no honour, acts in bad faith."
He says the Government is trying to rewrite the Treaty of Waitangi.
