The Earthquake Commission has confirmed it's halving in size from next year as it winds down its Canterbury quake work.
It says it will go from an organisation of 868 positions, down to 458 in 2017, a loss of 410 positions.
A restructure proposal went out to staff in August for consultation and has now been confirmed.
The new structure leaves 75 more jobs in place than originally proposed.
The changes will affect staff on fixed term contracts due to expire in December this year, or on contracts for service.
The bulk of the roles – 185 - will be lost in Wellington, while around 150 will go in Canterbury and 75 will go in Hamilton.
EQC says a focus for the organisation in 2017 will be getting through remedial repairs.
As of August it was still receiving 70 remedial repair requests a week but said that number was trending down.
