"There are some quite significant businesses coming back into the CBD like Trustpower, which is great. Hopefully in the not-too-distant future the university campus will set up and we are also aware of other potential developments and redevelopments."
Ratepayers would not foot the bill as it would be user pays, he said.
"The parking buildings are paid for by parking fees ... if it went ahead a loan would be taken out.

"If you have all these new things coming into town you are going to need extra parking. "
Books A Plenty owner Chris Baskett said there was a positive vibe in the CBD and the shop had rolled over its lease.
Meanwhile, Brooklyn Patio and Eatery owner Dean Teddy said he was all for growth but he questioned the $5 million price tag on the carpark.

Confidence had lifted but it was city-wide not necessarily just in the CBD, he said.
The proposal
