An owner-operated New Zealand business bringing engineering judgement, verified supply relationships, and practical deployment experience to Bitcoin mining and digital heating.
What began as an early interest in peer-to-peer money developed through physical builds, published research, factory visits, and working heat-reuse systems. These are the milestones that shaped ASIC.NZ.
While still at school, I first heard about Bitcoin from a good friend as we waited in line at the tuck shop. He described how peer-to-peer money could move value outside traditional banking rails and capital controls. That conversation led me to construct my first Bitcoin transaction later in 2013.
Designed a Raspberry Pi and LED-matrix ticker that retrieved live exchange data and presented cryptocurrency prices as a physical, continuously scrolling market display.
Developed PLEB-TNAK, an immersion cooling system for Bitcoin mining hardware, on 9 January 2022—turning an interest in mining infrastructure into a practical engineering project.
Authored “Intelligent Self-Consumption System: Heating homes for free, recycling waste energy, and improving solar system ROI” on 2 May 2022—an early foundation for the digital-heating work pursued today.
Maintained direct involvement with the regional cryptocurrency industry through AusCryptoCon in Melbourne, two subsequent conventions in Sydney, and the inaugural NZCryptoCon in Auckland.

Imported New Zealand’s first off-the-shelf immersion cooling product—a Fog Hashing C2—a 12 kW system designed to accommodate two miners—for a customer in the South Island. Since that first deployment, several more C2 systems have been imported for New Zealand operators.
Travelled to Chengdu to visit HeatCore, Xi’an to visit Fog Hashing, and Shenzhen to visit Shenzhen Letine Technology Co. These visits provided the opportunity to inspect their operations and establish the face-to-face relationships that now underpin ASIC.NZ’s supplier network.
Published the PLEB-TNAK V2 and PLEB-SAC repositories on GitHub on 30 July 2024, documenting an evolution of the original immersion system and an applied approach to sound attenuation for mining hardware.
Used a Fog Hashing C2 to maintain a spa pool at 38°C, 24 hours a day, for several months. Built a custom dashboard to monitor water temperature and energy use remotely, turning the installation into a measured, real-world digital-heating system.
Incorporated ASIC.NZ on 19 May 2025, bringing mining hardware supply, engineering support, digital heating, and direct manufacturer relationships together for New Zealand operators.
Visited Grid Share’s mining operation at Lake Monowai in Southland’s Fiordland region, approximately 67 km from Te Anau. Grid Share builds and operates flexible, power-responsive data centres that can adjust their demand to suit grid conditions. The visit provided a direct view of this model operating alongside one of New Zealand’s oldest hydroelectric schemes.
Attended Bitcoin MENA in Abu Dhabi and the WhatsMiner M7X Series Launch Event, extending direct exposure to current mining technology and the international manufacturer ecosystem.
A New Zealand client became the country’s first customer to take delivery of a 24 kW immersion cooling system: the Fog Hashing C6. The C6 accommodates six miners—three times as many units as the C2—and is being integrated with an in-ground swimming pool so its mining heat can be captured and put to productive use.
