Mr McGarry said he was dealing only with the Harbourside property and had no knowledge of any other assets that might be still held by Mr Armstrong.
However, a well-placed source said the Harbourside property was believed to be the last remaining Tauranga asset of Mr Armstrong, who was listed as bankrupt under his full name of Lincoln Shane Douglas Armstrong in 2012.
Mr Armstrong established the Grumpy Mole Saloon chain and owned a number of Tauranga bars, restaurants and commercial properties before his business was affected by the global financial crisis.
Peter and Anita Ward bought the Harbourside Restaurant off Mr Armstrong in 2011, after managing it for over four years.
"We have a long-term tenancy and we're looking forward to carrying on as usual, regardless of who acquires the building," said Mr Ward.
Harbourside Restaurant holds a 10-year lease to the property, which commenced in 2011, with the right to renew its lease for two further terms of 10 years each.
This gives a possible final expiry of September 2041. Two other tenants hold shorter-term leases to office spaces upstairs, contributing to the total gross annual rental income of $162,000. Adjoining car parks, owned by Tauranga City Council, are also offered for lease.
