Weekends are a big distraction for Bay workers, many of whom switch off two hours before the end of work on Friday.
Colmar Brunton research shows workers in the Bay tend to drop down a gear at 2.58pm on Friday, half-an-hour before the national average of 3.29pm.
Bay workers also leave the office 15 minutes earlier than the national average of 3.50pm.
The research, commissioned by Mitre 10 and conducted in August, looked at New Zealanders' habits in anticipation of the weekend.
Key findings nationally included 41 per cent of respondents said they avoided dealing with difficult tasks on a Friday in anticipation of the weekend and 64 per cent spent the last two hours of work arranging weekend plans.
