Should parties offer money or prizes to people to enrol?

The Greens are offering:

Enrol to vote and be in the draw to win cool prizes, including a custom-fitted bike, in our Mobilising Aotearoa Competition!

I think it is very much a thin end of the wedge to have political parties offering money or prizes to people to enrol. Even worse, there appears to be no checking that said person actually enrols, or was not already enrolled.

Think if you had MPs or candidates knocking on people’s doors handing out cash if residents there promised to go off and enrol?
