Mr Bunny said it would be "business as usual" for the trust, which was in the process of bringing the new trustees up to speed.
"It's ... managing property in a way that maximises the financial returns through educational, cultural and community grants.
"We're always looking for new projects and aim to continue to grow the community assets in our care."
Mr Bunny has historical ties to the 142-year-old public lands trust, which was formed to own and manage surplus land that was not sold to Masterton's working-class settlers.
It operates under its own Act of Parliament - the Masterton Trust Lands Act.
Mr Bunny's great grandfather, Henry Bunny, was the member of the provincial council for Wairarapa who proposed the original Lands Act that created the Masterton Lands Trust, through Parliament, in the 1870s.
His grandfather, Arthur Bunny, was also the solicitor for the trust for 30 years.
"I have got very strong connections historically. I just see my role as carrying on the work that has been done before, through generations."
Mr Bunny is also a Justice of the Peace, a Wairarapa Rescue Trust trustee and is on the finance committee of St Patrick's Church.
Property assets owned by the Masterton community through the trust hit a record $62.7 million this year.
