Covenant posted revenue of $6.17m and net profit of $2.19m for the same reporting period.
Tricor serves over 50,000 client entities in 21 markets globally, including 20,000 clients in mainland China. It said in a statement it planned to invest further in the Guardian and Covenant businesses and all staff will remain in place as day to day operations remained unchanged.
"We're excited to welcome Guardian Trust and Covenant to the Tricor family and have been very impressed with the local management team led by NZGT Holdings CEO Harry Koprivcic," Tricor Group CEO Lennard Yong said.
Complectus began buying trustee firms in 2013 with the acquisition of Perpetual Trust before adding Guardian and Covenant to its stable. The group also includes Foundation Corporate Trust and New Zealand Trustee Services.
Barnes had planned to raise $150m in a public float of the company in 2016 but put it off citing volatility in the markets at the time.
Direct Capital emerged as a half owner of Complectus in 2019 after exercising a convertible loan issued in 2017 in a deal that valued the company at almost $130m.
Koprivcic says the decision to join forces with Tricor was strongly driven by the firm's global reputation and recognised strength in corporate services.
"Sharing in Tricor's service-oriented approach and benefiting from their investment, we will continue to grow our team and capabilities to support the delivery of our market-leading supervisory and trustee services to the New Zealand market."
