There’s been a security breach and the site has been temporarily shut down to investigate the issue.

A privacy glitch in NZ Post’s overseas freight-forwarding website YouShop has exposed users’ credit card details, mailing addresses and lists of goods sent and received to other users.
Wellington man Ian Tan spotted the bug a week ago when he navigated away from his YouShop account then came back to it. The flaw eventually revealed three other users’ details – including partial credit card numbers, where they lived and a manifest of posted items.
Last night NZ Post shut down the site as technicians worked to isolate the problem.
