The Transport Minister is focused on building essential infrastructure as the Auckland Regional Fuel Tax is scrapped.

Auckland motorists will save 11.5 cents a litre, with the tax removed from tomorrow.

Simeon Brown says hundreds of millions of dollars from the tax wasn't being spent at all.

"We're stopping the waste, we're focusing it back on the basics. And that remaining funding is going to go towards priority projects, such as the Eastern busway, more trains for the rail link and local roading upgrades."

He adds the Government isn't increasing fuel excise and road user charges in this term.

Joe Biden is unlikely to step aside from the US Presidential Election.

There are calls for him to stand down after he stumbled answering questions and didn't finish sentences in the debate with Donald Trump.

Many were calling it Biden's chance to prove his physical and mental fitness for another Presidential term.

Canterbury University Political Science and International Relations professor Alex Tan says it would be messy for a new presidential candidate to step in.

"There are others that could, but I'm not sure any of them would want to go into a situation like that."
