The role of foreign investment is largely overseen by Auckland Tourism, Events and Economic Development(Ateed), which has a former senior executive, Grant Jenkins, based in London, and a staff member, Pam Ford, based in San Francisco with New Zealand Foreign Affairs and Trade(MFAT).
Mr Jenkins' role is costing ratepayers about $230,000 for an initial 12-month contract.
Most of Ms Ford's salary is being paid by MFAT, although figures released under the Official Information Act show ratepayers paid $35,484 for an accommodation supplement between April 2014 and February 2015.
Ateed also has an officer, Edwina Mason, based in Melbourne to secure conferences for the city.
Her salary is funded by the Auckland Convention Bureau.
In the first term of the Super City, councillor and Olympian Sir John Walker was appointed by Mayor Len Brown as the city ambassador.
Councillor George Wood, who chairs the council committee overseeing economic development, said he was not privy to any appointment of Sir Bob to the role of city ambassador.
"This is a major departure from the normal role of council to appoint someone to a role like this, if it is correct," Mr Wood said.
