You must use the email address that your HR manager provided us, and it must be entered exactly the same. Look out for is a 'space' at the end of your email address, for example, "name@example.co.nz " should be "name@example.co.nz". If there is a space at the end of your email, an error will show, and you will not be able to register.
If you are still having issues, please contact your HR manager.
