Police say this year's Waitangi Day celebrations in the Bay of Islands were among the quietest on record.
Organisers estimate a record crowd of between 40,000 and 50,000 people were at Waitangi on Friday.
However, there were no arrests at the Treaty grounds.
Inspector Chris Scahill says more than 100 police officers were at Waitangi this year.
He says people have adopted a more mature attitude to Waitangi Day and what it stands for.
Inspector Scahill says the event has become more peaceful and family-focused in the past few years.
Friday was the anniversary of the signing of the Treaty of Waitangi on 6 February, 1840. The Treaty is New Zealand's founding document.
