Mr Manuel said while he did not head to Wellington as he was awaiting an operation, about 20 iwi representatives had gone. Many more had booked flights and accommodation weeks before, including one who was going to come from Australia, but decided to stay home after it was announced the passing of the bill had been delayed.
Leader of the House Gerry Brownlee and Minister for Treaty of Waitangi Negotiations Christopher Finlayson said appalling behaviour by New Zealand First was the reason why the passing of the bills was abandoned.
The party's opposition meant a formal party vote would have to be taken rather than a unanimous voice vote, which would require more MPs in Parliament.
However, New Zealand First leader Winston Peters said National had the numbers to vote to go into urgency or extended hours and pass the bills. He said given the Government knew iwi were arriving that is exactly what it should have done.
Mr Manuel said there were a "heck of a lot of people unhappy with Mr Peters".
"It's a bit of a sting. It's frustrating because he had every opportunity to raise issues following the first readings."
But Mr Manuel also said he wished the Government had gone into extended hours to see the bill passed.
"That would have been nice. But we've come this far and there's no turning back. We've waited 30 years, a little bit longer is not going to hurt," he said.
Mr Peters also said passing the Ngatikahu Ki Whangaroa claims settlement bill would be a serious mistake as hapu Ngati Aukiwa say Stony Creek Station should be returned to their hapu, not the whole iwi as the settlement bill requires.
However, Mr Manuel disagreed and said there were many hapu connected to Stony Creek Station.
