In 1983, Prince Charles and Princess Diana opened the visitor centre at the Waitangi Treaty Grounds.
They probably accounted for a decent proportion of tourists that year, and while the rest of the tourism attractions in the area have progressed, the centre hasn't moved at the same rate.
However, the Waitangi National Trust has started on a $1.7 million project that will see the visitor centre made bigger and better.
It's a long overdue investment and reflects the importance of tourism as a pillar that holds up this region's economy.
And it had to happen, to keep in step with other growth, like the $14 million Te Kongahu Museum of Waitangi that opened in February.
