Following three days of negotiations, the unions representing Air New Zealand logistics and engineering workers have come to an agreement in principle.
The mediated negotiations come after strikes were threatened by staff which would disrupt travel over three days from Friday, December 21.
The three days would disrupt travel for 120,000 customers over the three days which are the busiest days in the airline annual calendar.
Air New Zealand chief ground operations officer Carrie Hurihanganui said the airline was focused on achieving a resolution on behalf of its customers.
"We know how important it is to our customers to get where they need to be, particularly at this special time of the year, and the negotiating teams have been working diligently to achieve this result."
