Both are Australian citizens.
The SFO alleges between November 2013 and June 2017 the guilty party received contracts of more than $20m of work on the recommendation of the second defendant, paying kickbacks of approximately $4.1m in exchange for receiving the work.
The SFO alleges the two parties had a prior relationship.
“This case highlights the serious harm caused when an individual abuses their position of trust for personal gain,” SFO director Karen Chang said.
“The payment of over $4m in kickbacks not only undermines the integrity of our business sector but also erodes public confidence in the fairness of New Zealand’s business practices.
“The SFO is committed to holding those accountable who threaten the values of transparency and fairness that New Zealand is known for.”
