However, yesterday, Tong said councillors would have to discuss the matter again to see if it was still possible to keep the increase at that level, given the situation they now faced.
"We are very disappointed and frustrated," he said.
"It is a big shortfall."
The council did receive an increase in funding, but it was below what it had asked for.
"Council is very frustrated with this process and will be talking further with Waka Kotahi and the Government.
"The timing, in particular, is a major issue for us."
Councillors will make a final decision about the matter on Tuesday at a finance and assurance committee meeting.
