How can I fix 404 errors on my updated 2.0 Expanse site?

[LittleTallTales]

Hi,

We have just gone live with an updated site on 2.0 using Expanse and am seeing a couple of broken links, they are:

https://websiteurl/en-nz/localization

and

https://websiteurl/localization

What do I need to do to stop these 404 errors etc as I am not sure I should be redirecting them and if I did where to?

Thanks

Alan
