"The Tauranga investment means significant growth for the organisation and it's fantastic to have someone with his expertise managing the new business alongside our existing properties."
Mr Orchard said he was looking forward to getting his teeth into his new role.
"Whether it's continuing to provide great housing to people with disabilities or to the rapidly increasing number of people needing social housing, I know what a difference a good home makes.
"This is an exciting time to be leading this already strong organisation."
Accessible Properties signed a contract with the Government in December to become the landlords for 1140 Tauranga homes, currently managed by Housing New Zealand, from April 1.
Accessible Properties is a wholly owned subsidiary of IHC, which has been in housing for more than 60 years.
From April, Accessible Properties will manage more than 2700 properties including about 2500 homes, many owned by IHC.
