Blakeley said if any services are cancelled because of the stop-work meeting it will be posted on the Metlink website and app.
He said the meeting would not affect school services but will impact some customers using off-peak services.
"We will keep customers updated through our website and social media channels, as well as through public information on the radio.
"The key thing for customers is to please check before you travel. Use Metlink's app or website to check for cancelled services, or call our Metlink team on 0800 801 700.
