"You made such incredible music, were a true pioneer in the scene, did so much to help so many people in the music industry and you will never be forgotten. Catch some big fish up there big fella xx," she shared.
Monds' sister Casey wrote in a Facebook post last night: "I am utterly devastated to share the news that my big brother Jay passed away tonight.
"We miss him so incredibly much. Your messages of love, stories of mischief, mayhem, his laugh, his cheeky smile, the glint in his eye - these have been so comforting to us in these past few days. Thank you."
Others took to Twitter to share their tributes and memories of the DJ known as a pioneer of Aotearoa's drum and bass scene.
Damian Christie took to Twitter to pay tribute to his friend Jay Monds.
"I am heartbroken. Jay was a pioneer in the drum n bass community, a proud Dad and a loyal friend. He was also an amazing drone pilot, which is how we became so close over the last decade," he wrote.
Bulletproof's fan and fellow DJ Jimmy B Rollin told the Herald Monds' love and support of New Zealand music was "second to none".
"Jay was a pioneer of DnB [drum and bass] in this country.
"His passing has left a hole in the scene that can never be filled. His History of New Zealand Drum and Bass was an amazing gift."
