The airline industry is nothing if not ever-changing. Just eight years ago, Air New Zealand was pulling out of Singapore, and the island state's government was urging Singapore Airlines to pursue links with Qantas. According to Air NZ's then chief executive, Rob Fyfe, Singapore was a very small market and most of the airline's passengers would be equally well-served by travelling through Hong Kong.
Now, however, Singapore has become very much the focus as Air NZ bolsters its position on routes in the booming Asia-Pacific region.
The vehicle for this expansion is an alliance with Singapore Airlines, which, through codesharing and sales co-ordination, gives Air NZ access to the Singapore carrier's huge Southeast Asian network - including its SilkAir subsidiary - and beyond to India, Africa, Britain and Europe.
Additionally, Air NZ will resume flying its own aircraft between Auckland and Singapore, taking more than half of the flights operated by Singapore Airlines, and share revenue with the Singaporean carrier from all flights on the route.
The closer tie-up represents not only a return to Southeast Asia after a period of focus further north but confirmation that Air NZ is intent on growth. It has been seeking new partnerships rather than operating alone as a small carrier, albeit one that will be strengthened by the delivery of the first of 10 new Boeing Dreamliners in mid-year. Singapore Airlines had become a logical candidate.
