There are no plans to upgrade Auckland Transport's $2.2 million computer system after reports that Auckland City is spending tens of millions of dollars on bolstering a similar system.
Chief finance officer Andrew McKenzie has defended the council's expensive computer system, which councillor Mike Lee said could turn into a "monumental financial scandal" for the council.
Mr McKenzie said the $54 million computer system was built by the agency setting up the Super City to provide core services from day one for the Auckland Council and required additional upgrades across a range of functions.
In August, councillors approved an extra $12 million for an upgrade to asset management and property management functions and last week an extra $7 million for procurement and purchasing improvements. That brings the cost to $73 million with tens of millions of dollars of extra spending still to come.
Mr McKenzie said the council's system was not a clunker but a world-acknowledged financial system.
