However, in May 2010 a structure change in the police communications centres meant Ms Teding van Berkhout was asked to work a new roster so she would be in line with other staff.
She argued that the new hours were "not family friendly" because they conflicted with hours worked by her husband, Davitt, who was also a police officer.
Negotiations about her new rosters failed, and Ms Teding van Berkhout said she felt she had no option but to sign the new agreement because New Zealand Police had refused to consider her annual leave application until she did so.
ERA member David Appleton ruled that Ms Teding van Berkhout was "put ... in a position where she either had to work full time hours or work a roster which caused her significant problems with managing her family life".
"She chose the latter option, which led directly to her resigning because of those resultant problems," Mr Appleton said.
He ruled that because Ms Teding van Berkhout's bosses failed to resolve the problem after it was raised, her constructive dismissal was unjustified.
Ms Teding was awarded $9,287.20 for three months of lost wages and $10,000 for "humiliation, loss of dignity and injury to her feelings".
