Destiny's Church leader Brian Tamaki has got stuck into immigrants and Jacinda Ardern in a wide-ranging sermon at Waitangi.

He arrived with about 200 supporters, including his wife Hannah, and was one of many who spoke to the crowd of about 1500 people at an interdenominational service at Whare Rūnanga on the Upper Treaty Grounds.

They held signs reading "you can not plan tomorrow while fighting yesterday" with "Apostle Bishop Brian Tamaki" written in the corner.

Tamaki was invited to speak, as one of the church leaders, and the crowd cheered when he was mentioned.

"We live in a land with enough for everyone," Tamaki said.

"If it's not sold, extorted.

"One hundred and eighty years ago this land was given to all of us.

"But by 1975, Māori had lost 97 per cent of our land. God had prepared the land so everyone could live well healthy and long. But when we see the depravation and poverty now, people not living in that land, not living with dignity...

"Poverty under Jacinda Ardern hasn't been reduced, it's got worse. The number of people in prison has got worse."

Prime Minister Ardern had returned to Auckland after attending this morning's dawn service and a breakfast barbecue.

Tamaki continued: "Some of the people standing in line for welfare are immigrants, don't start me on that, we're not looking after our own.

"Putting money into the problem doesn't solve the problem.

"How are we helping the people who need it most? After 30 years of settlements?"

"We will only move on when parliament stops recolonising by selling off land to overseas investors, Japanese investors...

"This government has been the worst at selling off land to foreigners. If they've got that much land to sell they should give it back to Māori."

He said it was "disgraceful" that government agencies waited outside birthing suites to take babies away.

Seats filled fast on the paepae and the crowd included Army officers and ministers of different faiths.

Destiny followers, mostly in black "raising fathers to save lives" T-shirts, ringed the crowd. Women wore T-shirts saying "legacy sisterhood empowerment".

Hātea Kapa Haka from Whangārei supported the service with chants and waiata.
