How to Fix the BNZ App Not Working Issue

Now that we know the possible reasons, let’s go through the best troubleshooting steps to fix the BNZ app.

1. Check If BNZ is Down

Sometimes, the issue isn’t on your end—BNZ’s servers may be down due to maintenance or technical problems.

🔹 How to Check:

• Visit BNZ’s Status Page to check for reported issues.
• Check Downdetector NZ for outage reports.
• Visit BNZ’s official Twitter (@BNZ) for updates.

✅ If BNZ is experiencing issues, you may need to wait until their team fixes it.

2. Restart the BNZ App and Your Phone

A quick restart can clear temporary glitches that might be causing the issue.

🔹 How to Restart:

• On iPhone: Swipe up (or double-tap Home on older models) and swipe away the BNZ app.
• On Android: Go to Settings > Apps > BNZ > Force Stop, then reopen it.
• Restart your phone to refresh system processes.

✅ This simple fix works for many users!

3. Check Your Internet Connection

The BNZ app requires a stable internet connection. If it’s loading slowly or failing to connect, check your network.

🔹 Try These Fixes:

• Switch between Wi-Fi and mobile data.
• Restart your router and reconnect.
• Turn on Airplane Mode for a few seconds, then turn it off.
• Try loading other apps or websites to check if your internet is working.

✅ If other apps also don’t work, the issue is with your internet.

4. Update the BNZ App

An outdated BNZ app version can cause login errors or app malfunctions.

🔹 How to Update:

• For iPhone: Open the App Store > Search for BNZ > Tap Update (if available).
• For Android: Open the Google Play Store > Search for BNZ > Tap Update.

✅ Keeping the app updated ensures you get the latest security patches and bug fixes.

5. Clear Cache and Data (Android Only)

If BNZ keeps crashing or lagging, clearing cached data can help fix corrupted files.

🔹 How to Clear Cache:

1. Go to Settings > Apps > BNZ.
2. Tap on Storage & Cache.
3. Select Clear Cache (this won’t delete login info).
4. If the issue persists, tap Clear Data (you’ll have to log in again).

🔹 For iPhone Users: You’ll need to delete and reinstall the app to clear cache.

✅ This often fixes persistent issues!

6. Check Device Compatibility

The BNZ app may not work properly on older phones.

🔹 How to Check:

• For iPhone: Go to Settings > General > Software Update and update iOS.
• For Android: Go to Settings > System > Software Update and check for updates.

✅ If your phone is too old, you may need to access BNZ via a web browser instead.

7. Disable VPN or Proxy

VPNs and proxies can interfere with banking apps for security reasons.

🔹 What to Do:

• Disable your VPN and try logging into BNZ again.
• If on a work or school network, switch to mobile data instead.

✅ If VPN interference is the issue, this should resolve it.

8. Reinstall the BNZ App

If all else fails, reinstalling the app can fix corrupted files or installation issues.

🔹 How to Reinstall:

1. Uninstall BNZ from your phone.
2. Restart your device.
3. Reinstall BNZ from the App Store or Google Play Store.
