If you are experiencing issues logging in to your Air New Zealand account with a new password, follow these steps to troubleshoot and resolve the problem:

1. Verify Username and Password: Ensure that you are entering the correct username and the new password. Typographical errors can easily occur.

2. Reset Your Password: If you suspect that the new password is incorrect or if you are still having trouble, proceed to reset it. Visit the password reset page: Forgot Password - [learn more]. Enter your username and submit your request to receive a password reset email.

3. Check Email: After requesting a password reset, check your email for instructions. Make sure to also check your spam or junk folder in case the email didn't appear in your inbox.

4. Re-enter New Password: When prompted during the password reset process, create a new password. Ensure that it meets the required criteria (e.g., length, complexity) as outlined on the site.

5. Clear Browser Cache: If you are still unable to log in, it may help to clear your browser's cache. This can resolve any issues related to stored data.

6. Try Different Browser or Device: If the issue persists, attempt to log in using a different web browser or device to rule out any platform-specific problems.

7. Disable VPN and Browser Extensions: Sometimes VPNs or certain browser extensions can interfere with login processes. Try disabling them temporarily and then attempt to log in again.

8. Two-factor Authentication Issues: If you have two-factor authentication (MFA) set up, ensure that you are following the additional verification steps correctly. Visit your profile to manage your MFA settings if needed - learn more - [learn more].
