Rob Ruha is a multi-award-winning singer and songwriter, chosen as a music director for this year's Silver Scrolls.
His latest album Preservation of Scenery is out today, but it's the song '35' that launched the New Zealand artist onto the global stage.
With a little help from fans on TikTok - and Ka Hao - the track has been streamed millions of times.
And on The Project's Te Wiki o te reo Māori show, Ruha and his crew reunited to perform '35' live in the studio.
