Some ASB Bank (New Zealand) customers may have received a security notice email warning about a login from the United States of America.
These logins are a normal part of the bank feed syncing process, run by our upstream provider Yodlee. The security notices are being sent because of a change Yodlee have made to the location they connect to ASB Bank from. They are currently connecting to ASB from their United States-based cloud, rather than locally from Australia/New Zealand.
We are working with Yodlee to revert back to connecting to ASB locally, which should stop the security warning emails from being sent.
