Split shifts are a very common method of working, especially in the Transportation Industry. In order to record a split shift you first need to have a good understanding of the NZ Work Time Rules.
In summary, since you a required to have a continuous rest break of 10 hours within a 24 hour period you only have 14 hours available to work.
For example if you started your first work period at 6 am, you would need to finish your work day by 8pm to make sure you have 10 hours of rest.
The structure of that 14 hour window is completely up to you as a driver.
Pro tip: Your digital logbook is like a time card; by starting a shift you are opening up your work day and by ending it you are closing your work day
To reflect "split shift work" in your digital logbook:
Start your shift when you begin your work day and work for as long as desired (including rest breaks if needed)
When you want to "end you first shift for the day" take a rest break (DO NOT END SHIFT)
When you want to "start your second shift of the day" simply click Drive or Other Duties to resume your work period.
When you are finished all work for the day and can commit to a continuous 10 hour rest break click the "End Shift" button.
