Gravity got the better of the Lotto balls in tonight's Powerball draw.

The number six was drawn by the Powerball machine, before being knocked off the pipe by the other balls spinning in the machine.

"This is the Powerball number you need to make it happen. There it is - Powerball number six. Congratulations to all our winners," host Sonia Gray said, before turning around to see the number had fallen out of the pipe.

"OK, unfortunately we appear to be suffering, experiencing some technical difficulties. The remainder of the draw will now be conducted off-air under audit scrutiny."

The Powerball number from the audited off-air draw is 01.

One lucky player from the Waikato won $1 million with Lotto First Division. The ticket was bought online.

Powerball rolls over to $6 million on Wednesday night.
