Cannot see or edit my own listing

Most likely it's being reviewed before listing as it's a high price often listed by scammers item. Give it time, but if still showing as invalid tomorrow morning, get in touch with Trademe via live chat. Also check your emails including spam folders in case Trademe have emailed you asking for proof of ownership/possession.

Thanks @Gary-NZStocked , that seems to be the problem, I received an e-mail from trademe and have replied them with relevant information. Thanks for that!

Good one Ming. It's just a security thing they do sometimes. Good luck with your auction :)

Update. Good to see it's all cleared now and active.

I get the same problem as well
