"The number of workers expecting a pay increase over the coming year has fallen to its lowest level since the survey began in 2004," Ranchhod said.
"This is a particular concern as the recent fall in the New Zealand dollar will result in the prices for many goods pushing higher over the coming months. As a result, many households may find their budgets becoming increasingly stretched over the coming year."
Across 11 regions, seven recorded a decline in employment confidence, with the gloomiest sentiment in Northland, which became slightly less pessimistic in the third quarter at 91.6 compared with 90.2 three months earlier.
In Auckland, confidence dropped to 100.7 from 107.8, holding just above the 100 level that separates optimists from pessimists.
Waikato's confidence fell to 96 from 96.7.
Ranchhod said challenges in the dairy and forestry sectors were weighing on confidence in regions such as Northland, where they are major employers.
