New Zealand's official top 40 music chart will, for the first time, include on demand audio streaming.

The change happens from tomorrow, and has happened as streaming increasingly becomes an important method of music consumption.

Recorded Music NZ boss Damian Vaughan says it's seeing rapid adoption by music consumers.

Music streaming revenues have tripled since 2012.

Between us all, New Zealanders stream an average of three million tracks per day.

The top three most streamed artists here are Ed Sheeran, Eminem, and Lorde.
