The report also found a total of 4295 full-time equivalent jobs were generated by the industry last year.
Recorded Music NZ chief executive Damian Vaughan said the findings showed continued gradual growth since stakeholders commissioned their first report on the industry's contribution to the economy last year. "It's fantastic. It's a growth industry, albeit one facing challenges in different areas," he told the Herald on Sunday.
"Our part of the industry, recorded music, is facing the piracy challenge. The decline in revenues in that area is not new, but we're optimistic we're turning a corner."
Streaming - which allows subscribers to access music at any time - had trumped illegal options, Vaughan said.
"What we've found is the services that exist now are better propositions than the rigmarole of going through music piracy. Our sector is very hopeful that we're going to forecast growth [in retail sales] this year, which will be the first time in 15 years."
Retail sales - including streaming services - in New Zealand peaked in 2001 at about $120m.
Last year, sales of Kiwi artists directly contributed $54m to the economy.
Music radio broadcasting accounted for the largest chunk of the $472m generated by the music industry, with more than half coming from the medium.
Live music generated $120m, while the smallest contributions came from communication and performance, at $33m. New Zealand's GDP was $217 billion in the June 2015 quarter.
