Create New Auto Publishes even as a contributor

When a user logs in as a contributor (access we give all members when they sign up) their wiki's they create from the backend are moderated and an editor or higher has to approve them. However when they create one from the "create new" tab of an existing wiki it auto approves it.

The "create new" tab is what most of our users are using and this is causing havoc for our editors.

I need to lock this down ASAP.
