National's road user charges expansion won't be accomplished right away.  

It's proposing adding them to every vehicle including electric ones.

He told Kerre Woodham it will take a bit of time to get it exactly right. 

“There’s obviously a lot of work that will need to be done around the details to ensure that can be done in an efficient manner.”
