Wairarapa Chamber of Commerce chief executive Stephanie Gunderson-Reid said the lack of information was challenging. "I would have to say that it makes it difficult to get a feel for the region without that information," she said.
"We use a lot of demographic information so we're quite reliant on Statistics New Zealand."
South Wairarapa Mayor Adrienne Staples said it wasn't appropriate to treat the Wairarapa as part of Greater Wellington. "We may be part of the Wellington region because someone has drawn a line on the map but we are a very different province - quite different to our metropolitan cousins over the hill.
"Lots of people are locally employed and the situation's very different."
But Carterton Mayor Ron Mark said he wasn't fazed by the lack of information. "We've been working a little blind for a while - we're all waiting for the census to be completed."
He said the Carterton District Council communicated closely with its public. "We are all pretty much in touch with the community. I don't find it hard to find out how much people earn - I'll just go and ask them."
Masterton Mayor Garry Daniell said he didn't feel the information was crucial.
