Shout out to our brothers on the NZ version of OzBargain, Choice Cheapies for this deal.
Budget NZ is having a 'Drive North for $1 per day' sale. Max hire length is two days but you can string some trips as separate bookings if you're organised. It says North Island but it works Queenstown to Christchurch. Also it's most of the car options so you can pick the big ones for the same price.
Example trips:
17 Jan Wellington Airport > 19 Jan Auckland Airport - Total $2NZ
1 Feb Queenstown Airport > 3 Feb Christchurch Airport - Total $2NZ
Very specific deal but if you have NZ travel plans this Summer it can save you plenty of money.
