going live

OK – so I have built my site on the host directory in a wp folder. My old site was in the root directory. Then I asked my host to make the site go live and delete the old html version. They didn’t really know what to do and ended up with some of the site, none of the pictures, a broken menu and wrong colours. They have restored it to the way it was and have told me to get WordPress help. Here it is now at https://www.charlotteswebdesign.co.nz/wp/

How can I get it to sit at https://www.charlotteswebdesign.co.nz ?

all advice greatly appreciated thanks
