Greenlea boss Tony Egan says blockchain technology addresses fraud and cyber-security fears.
ASB is claiming a first with a new blockchain-based service used to organise a meat export trade deal.
The bank says Greenlea used its new "single trade window" service to process a deal with a large Korean importer.
ASB's GM Global Transaction Banking Greg Beehre said the transaction was a landmark because the blockchain-based service meant digital payment and paperwork for the deal were wrapped up in an hour - compared to the two to four days it would take to process using more traditional means.
Trade is currently paperwork-heavy, Beehre says, making it susceptible to fraud or human error.
Greenlea boss Tony Egan says blockchain also appealed because of the technology was created to be unhackable. He notes that cybersecurity was one of the top concerns in the Herald's recent Mood of the Boardroom survey.
Egan says while Greenlea already had paperless systems, the single trade window solution meant it could move from scrabbling emails together to a single dashboard covering elements such as payment, regulatory documents and insurance, shipping and Customs paperwork.
He adds that by wrapping everything into one place, it's easier for an exporter to include and promote an export product's attributes. In Greenlea's case, that means highlight the fact its beef is pure grass-fed, and including information such as its product's farm of origin.
Blockchain was popularised as the transactional database technology that underpinned the digital currency bitcoin.
While bitcoin hype has fallen away following the Crypo-Currency's crash earlier this year, blockchain is gaining momentum.
Auckland University commercial law professor Alex Sims says blockchain's security and audit-friendly ability for all parties to transparently follow a series of transactions would push it into the mainstream.
