Fellow newcomer Moko Tepania, who at age 28 is Northland's youngest councillor, received the loudest cheers and whistles from supporters in the audience.
The Te Kura Kaupapa Māori o Kaikohe teacher said he was excited about what the council would achieve over the next three years.
"I'm looking forward to being able to represent Kaikohe-Hokianga and the Far North as a whole, and give back to the community," he said.
The other new councillors are Rachel Smith, a community board member in Kerikeri for the past three years, and Kaitaia businessman David Collard, who lost his seat after one term in 2016.
Meanwhile Cr Court said elected members and the senior leadership team would attend a two-day strategy meeting over the next two days, where "honest talks" would take place to lay the foundations for the next three years.
Mr Carter said he was looking forward to a productive year, and, at the inaugural meeting, asked councillors to approach him directly if there were any problems.
"I think the public selected a great team of people to work together," he said.
"But please, if you have an issue, put it on the table. We're here to deal with the issues and represent our community. It's not about us personally, it's about us collectively, working together."
