Northland's biggest dairy farmer, until he sold up last year, said the awards had been a great opportunity to meet other songwriters and musicians from around the world.
The awards success and exposure had also opened doors with media and radio.
New Zealand music already had a strong presence in California, with The Broods and Lorde in the line-up for this year's Coachella music festival, he said, adding that the recently released follow-up to OB, Wipe Out, had been well received so far.

The video was based on a true story, as told to him by a refugee who made contact after hearing OB. Merv said he had tried to capture the refugee's frustration and torment, and would donate the profits to World Vision's Children in Crisis.
He had enjoyed some success in the New Zealand rock music scene in the 1990s, he added, but had been able to dedicate more time to writing and recording since selling his farms.
The Akademia Music Awards are aimed at promoting lesser-known artists, giving them "a higher degree of market exposure and professional recognition for their work ... to take them from relative obscurity to commercial success."
