ACT leader David Seymour says the overwhelming majority of people at Waitangi were respectful during his address.
The National Trust chair has apologised to Seymour, MP Nicole McKee and Deputy Prime Minister Winston Peters.
All three were drowned out by jeers - and Pita Tipene says more effort should have been made to ensure they could express their views.
Seymour says many were listening politely.
"Unfortunately, it's one of those things where a small number of people ruined it for everyone. And it's really important to recognise this isn't all Māori who were doing this, this was a very small minority of people who don't represent much."
