A Maori business in Te Tau Ihu is warning the Crown not all South Island claims have been settled.
The Government has celebrated reaching agreements with iwi and hapu in Te Waipounamu.
But Wakatu Incorporation is waiting for the Court of Appeal to rule, after it took a civil case against the Crown, arguing wider Treaty settlements extinguish its claims to land.
Incorporation chair Paul Morgan said he's also tackled the Prime Minister about the issue.
He said he supports the Government's efforts to manage the economy, growth, and education.
But Mr Morgan said he's made it clear to John Key that Wakatu is not in sync with the Government's direction of claims in Te Tau Ihu.
