I think I might have found the answer as per Callum's response to this thread, so I'll wait and let the auction end and see if I could reimport them under my products, as suggested by Callum. Thanks Callum appreciated.  https://help.trademe.co.nz/hc/en-us/community/posts/11597557991065-Accidentally-deleted-My-Products-listings

Thanks Gary, this info helped, costed me ¢25 to edit and end the auction asap but yes I was able to import into my products. :)
