Prime Minister John Key says he has full confidence in his security team, despite being attacked on Thursday.
Mr Key was man-handled as he made his way on to Te Tii Marae at Waitangi.
He says slightly more security personel were following him on the Treaty grounds on Friday, but he doesn't want his security to become too extreme and curtail his activities.
Mr Key says the incident was a one-off random event from two people who "are out of step with the rest of New Zealand".
He says Waitangi Day has been a day of celebration and unity.
It is also the first time the Maori Party and the National Party have come to the Treaty grounds as a coalition Government.
Mr Key says the Waitangi commemorations have demonstrated that the Government is serious in business and that it's making progress.
He says Maori at Waitangi have also got a sense of the personal relationship he and deputy Prime Minister Bill English have with Maori Party leaders.
The Waitangi National Trust estimates 50,000 people are at Waitangi for Friday's events.
