The duo convicted in 2016 in New Zealand's largest bribery prosecution - involving more than a million dollars in kickbacks and tens of millions of dollars in roading contracts - have been released from prison.
According to decisions from the Parole Board, Stephen Borlase and Murray Noone were both recently granted early release after serving a third of their sentences.
Borlase, the former managing director of engineering firm Projenz, was found guilty of paying bribes to his co-accused and sentenced to five and a half years in prison.
Noone, a senior manager with Auckland Transport at the time of the offending, was given a five year sentence.
A seven-week trial heard of lavish entertainment spending by Projenz on Auckland Transport staff - including a 10-hour, $5500, long lunch at viaduct restaurant Euro - and a long-running financial relationship between the pair that saw more than $100,000 paid annually to Noone and disguised as "consulting" fees.
