Shepherd is an experienced, long-time local body politician who only a month ago was the council's chairman, while Yeoman is a one-term council member, first elected in 2016.
One result that was overturned from election night was in the Kaipara where Brian McEwing, a former Kaipara District councillor who held narrowly to the second seat for the Dargaville ward after Saturday's election, missed out after special votes were counted. McEwing misses out to incumbent Karen Joyce-Paki, who takes the second seat behind Eryn Wilson-Collins.
All the other election night results from the Kaipara remain the same.
The council will now comprise: Mayor: Dr Jason Smith; Kaiwaka-Mangawhai: Jonathan Larsen, Peter Wethey (both elected unopposed); Otamatea: Anna Curnow, Mark Vincent; Dargaville: Eryn Wilson-Collins, Karen Joyce-Paki; West Coast-Central: Victoria Del la Varis-Woodcock, David Wills.
A powhiri and inaugural meeting will start at 10am on October 25 at Dargaville Town Hall, with members of the community welcome. With special votes still to process, the final results were due to be announced on October 17, followed by the official declaration on October 21.
The inaugural meeting of the new KDC will be at Northern Wairoa War Memorial Hall, 37 Hokianga Rd, Dargaville, beginning with a pōwhiri at 10am on October 25.
There are not expected to be any other election-night results overturned in the other councils.
