If you want to take a break from contributing to Workplace Savings, that's no problem!

To cancel your future contributions: 

1. In your Hub, tap Save
2. Go to Settings
3. Head to the Savings rules section where you'll see Auto Save and Stream & Save
4. For each method you have switched on, tap and you'll see the option to Remove.

You then withdraw your existing funds from your Workplace Savings if you wish.
