The Waikato region registered the most complaints (216) followed by Southland (120) with the Bay of Plenty accounting for 53 complaints.
The Labour Inspectorate is working with the dairy farm sector to ensure all workers on lower salaries get the minimum wage for the hours they work. Generally, for recovery of arrears, the limitation period is six years. If an employer cannot provide wage and time records, the Employment Relations Authority can (unless the employer can prove otherwise) accept the employee's claim of wages paid and hours, days and times. Labour inspectorate central regional manager Kris Metcalf says inspectors began visiting dairy farms in August as part of a long-term operation to identify breaches of employment law. Its focus is on raising awareness of a practice involving seasonal averaging of salaries and the failure to keep accurate time and wage records.
Bay of Plenty Farms would be included. Dairy NZ team leader Jane Muir says farmers know employees are critical to their success and they need to provide good working conditions.
Most farmers support the ministry's stance, which is targeted at the practice of seasonal averaging of the minimum wage, she says.
"At the moment, it's all about farmers understanding what the legislation is and making sure they are within it."
Dairy NZ is encouraging farmers to use time sheets because they are a great communication tool.
"It benefits the employer and employee to keep an accurate record of the hours worked on farm."
However, the difference for farms is that hours worked changed with the seasons, unlike in an office.
Federated Farmers employment spokeswoman Katie Milne says every industry has a range of good and bad employers.
The dairy industry is getting better at not being on the wrong end.
"We need to because the industry is growing and it needs to be seen as an attractive opportunity."
