Auctions are managed on behalf of the government by NZX and EEX (the European Energy Exchange).
NZUs at auction are sold to all successful bidders at the same auction clearing price. The clearing price of each auction can be found here on the ETS auctions site.

If NZUs remain unsold at the end of an auction they will roll-over to the next auction, provided it is in the same calendar year.
