It has been a record season for visitors to Waitangi.
And the Waitangi National Trust reports twice as many New Zealanders visited the Treaty grounds.
The trust introduced free entry for New Zealand residents last October.
Chief executive Jeanette Richardson says that's reduced gate-takings, but visitors are spending more on guided tours, concerts and other activities now on offer at Waitangi.
She says the trust predicted an increase in New Zealanders at the Treaty grounds, with free entry, but never expected the numbers to double.
The Treaty of Waitangi was signed on 6 February, 1840. It is regarded as New Zealand's founding document.
