You will need to access nUI+ to get those. Here's the link explaining how to get it.

However, if you already had access to it but now you don't the question is then. Did you download via the download tool either curse or wowi ? nUI+ is only available on WoWInterface and cannot be downloaded with the minion tool due to a glitch with how it recognises nUI and nUI+. This is resolved in version 6 but you have to manually downloaded nUI+ to keep it updated
