Rotorua's recently elected district councillors and community board members will swear to "faithfully and impartially" serve the community for the next three years at their first meeting.
The 10 members of the council and mayor Steve Chadwick will make and sign their official declarations before they take office from 10.30am tomorrow in the Rotorua Lakes Council chamber.
From 3pm tomorrow, the four members of the council's new Rural Community Board and the four members of its Lakes Community Board will also be sworn in for their three-year term.
Mrs Chadwick is also expected to make her inaugural speech before the rest of the council is sworn in and Dave Donaldson is officially appointed as her deputy.
Once that is done, the council will officially set the date for the first council meeting, set down for Wednesday from 9.30am.
