He said Statistics New Zealand reported that retail sales in the food and beverage sector had increased by 4.5 per cent from March to June 2014 and this was supported by a 5 per cent increase in accommodation spending over the same period.
"The improvements to the economy have encouraged consumer confidence and as a result we are seeing hot spots such as Ponsonby reap these growth benefits. Cafe, bar and restaurant sales are experiencing strong overall progression and the number of these food and beverage outlets is also increasing as a result of greater consumer spend."
Barton said the historic building's prime position and elevated site at the intersection of Ponsonby Rd, Jervois Rd, College Hill and St Mary's Rd had assisted its high occupancy rating.
It was designed in the Edwardian era by architect John Campbell and built in 1912, a period when the Auckland Chief Post Office, Old Town Hall and Ferry Building were also built.
The 100-year-old building is also connected with the murder of the Ponsonby postmaster in 1920 in a famous case internationally. It was the first time in the British Empire that the prosecution sought a conviction for a capital crime based almost entirely on fingerprint evidence.
Barton said Ponsonby was experiencing a resurgence as a "nightlife destination" with restaurants such as The Cav, Little Easy, Farina, and Boy and Bird restaurant all contributing.
"Residents of the affluent suburbs of Ponsonby, Freemans Bay and Herne Bay also don't need to travel far to enjoy whatever a new tenant decides to offer within this landmark building," he said.
