Mr Hudson was asked how much more the footbridge could deteriorate before it became unsafe.
"The report is telling you it is unsafe now," he replied.
It sparked Mayor Stuart Crosby to call for an immediate closure, saying he was not prepared to take the risk and rely on signs that might be misunderstood by foreigners.
He said it would be irresponsible to keep it open until it was fixed. There was enough evidence to say the footbridge was dangerous and he was not prepared to risk a tragedy.
"Safety is my priority," he said.
Mr Crosby was supported by councillors Larry Baldock, Tony Christiansen and Wayne Moultrie. Mr Moultrie said the last time he used the footbridge he thought it was dangerous and now there was a report to say it was dangerous.
"If we don't fix it, we are liable. It is a risk I am not prepared to take."
But most of the council opposed the move because of concerns it would lead to an even more unsafe situation.
They feared Matapihi residents would resume doing what they used to do before the footbridge was built 53 years ago - walking across between the railway tracks.
Councillor Bill Faulkner said closure risked going back to the situation that caused the footbridge to be built in the first place - people falling off the bridge and drowning.
Mr Crosby responded: "There is a thing called personal responsibility."
Councillor Rick Curach said that in the real world there was a high probability people would use the rail bridge and a tragedy could happen far sooner than if the footbridge was left open.
Councillor David Stewart said engineers were conservative and there was nothing in the report recommending closure.
The council agreed to get the repairs done urgently this year.
