"Part of the reason it's taken us a little bit longer to get out to New Zealand is because we wanted to make sure we did it right," Butcher told TimeOut.
"We've put a hell of a lot of work into making sure we have local music there ... we want to make sure everyone can find what they want."
That includes an exclusive NZ Top 40 app that will be updated weekly and allow listeners to stream heavy hitters on the singles charts.
And if a budding singer-songwriter wants to get their first song on Spotify without dealing with a label, all they need to do is visit the artists' page of the service's website and fill out a form.
"We want to make sure when a song is out, it's on Spotify. We believe that will stop people from going to torrent sites. We want it to be there from day one," says Butcher.
"We've ensured we've spoken to everyone and got everyone on board at launch because if you go on to a music service and search for your favourite band and can't find them, that's not a great experience."
Spotify's free service is available to everyone and subject to advertising. Spotify Unlimited costs $7.49 a month and is ad-free, and Spotify Premium costs $12.99 a month and gives access to music online or offline on a range of devices.
