Christchurch City Council's companies have been issued a directive to reduce the wage gap between its employees.
A letter of expectation has gone to the council's investment arm, Christchurch City Holdings, to close the gap between the highest- and lowest-paid employees.
The letter was made public after a vote and the matter was discussed in a public council meeting on Thursday.
Stand-in chairman James Daniels said the council made the call to talk about it publicly.
