The maintenance workers responsible for safety checks on Auckland Transport passenger trains have been locked out for 30 days, from 13 May, following industrial action. The dispute came about because of the difference in pay between the workers – contracted by Spanish multinational CAF (Construcciones y Auxiliares de Ferrocarriles) – and Kiwirail workers. The technicians receive about $7000pa less than Kiwirail workers doing the same job. The workers are asking for a 13 percent pay increase over two years. The counter-offer from the company is 5.5 over two years.
