The country's newest second level domain name (2LD), .geek.nz, has hit the ground running with over 270 names registered in the first hour.
No problems were reported with the launch, although some users who were trying to register common names that had already been taken were presented with an error message, says domain name commissioner Debbie Monahan.
"But no, we had no problems, no double-ups of registration, nothing like that."
The first name registered was registry.geek.nz, which went to domain name hosting company 2Day's Peter Mott.
"If you look you'll see we've got registry in all the 2LDs. It's a nice thing to have because people often type it in when looking for things."
Mott was surprised to see he was first to earn a .geek.nz name.
"The real geeks aren't going to buy these. This is going to be mother and sister buying a geeky name for the boy of the house. They're vanity names really."
The boom in sales continued all day and .geek.nz looks likely to overtake .maori.nz in the number of registrations if it continues to grow at that pace.
The man who bought the sought-after "linux.geek.nz" was Wellington-based Murray Fox.
"It was the geekiest thing I could think to get, I suppose," he says.
Fox, a Linux user, says he'll probably set up a site devoted to all things open source.
