Gibbard assumed his current role as group manager - environmental services in July 2020.
NRC chairwoman Penny Smart said Gibbard's appointment followed an exhaustive search.
"We were very pleased with the calibre of applicants for the chief executive - tumuaki role and Mr Gibbard stood out in terms of his in-depth knowledge of regional council work and his proven ability to lead in transformational change," Smart said.
Current chief executive Malcolm Nicolson will finish with the council at the end of September. Nicolson has been at the council's helm since early 2012.
Gibbard's appointment is part of the seismic change facing Northland local government leadership this year. He is one of three new Northland council chief executives taking the management helm between March and October.
NRC manages Northland's air, land, freshwater and coastal resources. It also coordinates civil defence, transport and economic development.
