It seems to be water pump, I have water tank in West Auckland.

 

Was doing some tests running the laundry water or the tap outside which has sign that says recycled water but the water meter still runs, so does the water from the tank gets pumped and also the water from main also gets pumps to keep the water pressure consistent? still saving water?

 

Without knowing the specifics of your setup, which can vary widely...

Laundry tap should be on town supply, though the laundry sink may be feeding a grey water system (which would be separate to the system suppling outside taps).

Your 'recycled water' system may have a mechanism to allow for a town water backup when the tank is low and/or pump isn't working. Some systems have a valve which just switches to town supply when the pump isn't feeding water (whether due to pump failure, power outage, or empty tank). Other systems have a ballcock in the water tank which fills up the tank when it's low, and then the pump ends up pumping the town supply water out of the tank and to the outside taps/toilet cisterns.
