The Clearance Warehouse is due to open this week in the Mid-City plaza which would absorb a large vacant area in central Napier outside the main-street survey area.
Napier Inner City Marketing manager Zoe Barnes said Napier retail was "tight", with the majority of areas full and development reflecting confidence in the future of CBD retail.
"There is a lot of development going on which has taken out retail stores, so that makes the rest of town tight but also shows there is definitely room to grow - people are seeing value in spending money in Napier," she said.
"Occupancy is probably as high as it has been for quite some time. Everybody is really positive - things are happening in Napier - it is a really good time to be in town."
The report said Taradale's main shopping precinct of Gloucester St had one less vacancy than the survey's previous quarter with five vacancies recorded, a medium-term average.
Hastings suburb Havelock North has seen supply increase by seven new shops thanks to The Exchange development - three now occupied - with seven vacancies overall for the Hastings suburb.
Last month Logan Stone director Frank Spencer said hospitality and non-retail operations were replacing traditional stores within all the region's key CBDs.
"Hospitality accounts for about a quarter of Havelock North and Taradale central premises, with further development in Havelock North to come," he said.
