Prime Minister John Key says it appears the Kingitanga movement did not lodge a claim for parts of Auckland by the 2008 deadline.
Waikato-based Maori King Tuheitia told those gathered at Ngaruawahia's Turangawaewae Marae on Friday, including Mr Key, he has launched a claim for much of the Auckland region.
"To actually make a claim you had to register by 2008 and we can't see anything at this point where they have registered," Mr Key told the Paul Henry programme.
However, the movement might prove them wrong or could go back and argue something else, Mr Key said.
"But lots of people claim things. I go to lots of maraes and people say we own this and we own that and actually proving that is a very different issue ... I can claim anything, I can claim I'm the Queen of Sheba."
The Kingitanga movement was also not a mandated group and they would need to be one to have a claim, he said.
On Friday, the king's spokesman Tukoroirangi Morgan said Treaty Negotiations Minister Chris Finlayson had agreed to hear the claim.
There were some Kingitanga rights from Warkworth into greater Auckland, Mr Morgan said.
He acknowledged Waikato-Tainui's claim would cause challenges with Auckland iwi.
Ngati Whatua spokesman Ngarimu Blair says the Auckland iwi acknowledges Kingitanga has interests in parts of wider Auckland.
"We just need to ensure new settlements don't undermine the existing settlements of others."
Under the Treaty of Waitangi Amendment Act, the Waitangi Tribunal is not permitted to register new claims or amendments to historical claims submitted after September 2, 2008.
