NZSDL is a pain in the @ss for us asx users.
You can avoid seeing this by clicking the link to the right near the top of the page titled customise.
The next step is to click on the edit button on the quick search line and then then cick on the drop down menu and choose Australian Securities Exchange and then click apply.
You will not see NZDL again when you do a new search after following these steps.
