"Aucklanders will be angered to learn that despite paying over half a billion dollars in Regional Fuel Tax, less than half of that money has actually been spent on transport projects in our city.
He added that it undermined claims made by the Government that the tax was essential for funding projects Aucklanders needed.
"This just shows what a sham this tax was right from the start.
"Aucklanders were told by the Government and Mayor Goff that this tax was needed to desperately fund projects which would help ease the congestion Aucklanders battle each and every day.
"Instead the tax revenue is simply being hoarded for projects which might be delivered sometime in the distant future," he said.
A spokesman for the council said there were "a number of reasons why the RFT [regional fuel tax] expenditure is currently lower than the money raised".
They said "spending will ramp up as projects move into the construction phase and all money raised for transport infrastructure will be spent for that purpose," adding that Covid-19 lockdowns and physical distancing on construction sites had also slowed up construction.
They said the council was constrained the types of projects it could fund.
"Central government legislation sets out which projects can receive funding from the RFT through an order in council.
"Any change to the list of projects that can receive RFT funding would need to go through a public consultation process and by way of an order in council by the Government," they said.
They added that the Government's decision to entirely fund a handful of Auckland transport projects under the NZ Upgrade programme meant they no longer needed fuel tax money.
An updated list of projects that might be funded with the money was put out for consultation last year.
It is not the first time the council has come under fire for failing to get projects going.
In December 2020, the Herald reported $156m from the tax had been unspent, about half the $330m raised at that time.
