"Everyone realises how important the Wairarapa is as a destination and they're all wanting to come and see it."
The length of time visitors were staying was particularly pleasing.
"We had over two nights average stay in July. That's really good news," he said.
"You only stay in a place longer if there's enough to do and there's plenty to do in the Wairarapa with the coast and the mountains and the town and villages and the wine and food."
National guest nights for July 2015 were 4 per cent higher than in July 2014, according to Statistics New Zealand.
Business indicators senior manager Neil Kelly said two-thirds of the rise for July was from North Island domestic guest nights.
"International guest nights and South Island guest nights also increased, but to a lesser extent."
For July 2015 compared with July 2014, North Island guest nights were up 5.7 per cent, and South Island guest nights were up 1.4 per cent.
