Ellis and Howard-Sager will both sit in the Family Courts in Whangārei and Kaikohe respectively.
Attorney-General David Parker said the new judges include replacements for retirements as well as 10 new positions.
Ten of the new judges are Māori, eight Pākehā, one Māori/Chinese and two Samoan. Twelve of the new judges are women.
"It's pleasing to see high quality appointees coming forward from diverse backgrounds. It is important that the judiciary reflects the make-up of the community it serves," Parker said.
He said the new judges would help manage the increasing workload in the District Court, improve access to justice and reduce the toll that long delays have on those accessing the courts.
The 2019 Wellbeing Budget allocated $54 million over four years to cover the cost of the new positions. That funding also covered the cost of the additional staff needed to ensure the judges can operate effectively.
Once the new judges are sworn in, the number of District Court judges will increase from the present 155 to 172.
The legislative cap on the number of district court judges was increased last year from 160 to 182 to allow for the new appointments and to leave room for 10 additional appointments in future years.
