Prime Minister John Key is expecting trouble at Waitangi when he visits Te Tii Marae for this year's Waitangi Day celebrations.
Key arrives at Waitangi on Wednesday morning.
He says it will be sad to protesters spoiling the day why he’s there.
He is aware of a hikoi protesting against deep-sea drilling, but says mining would be good for Northland's economy.
Green Party co-leader Metiria Turei says Key continues to promote the fallacy that people will be better off with deep-sea mining.
She says people have the right to protest against it.
