"That's good news for Hawke's Bay and for our members at the Port of Napier."
Mr Parslow said shipping companies didn't decide overnight to switch ports but, rather, they looked at the economics of where they could achieve the best deal.
"There's always a commercial reason, cheaper port and container rates.
"I don't think Fonterra woke up one morning and said let's go and take $27 million of export to Tauranga and Napier instead of through the Port of Auckland."
Union workers were looking for a lower pay rise of about 2.5 per cent, as opposed to the Port of Auckland's offer of a 10 per cent increase, in order to secure permanent long-term work, Mr Parslow said.
Port of Napier chief operating officer Chris Bain said Fonterra's move to Hawke's Bay would not automatically mean more jobs would be available at the port.
"If it becomes permanent change, and contributes to higher volumes in the longer term, then potentially yes, but at this stage I think we are within out capacity to handle the volume," Mr Bain said.
It would be fair to say that the Port of Napier would be looking to make the switch from Auckland "permanent business".
