Heard this "rumour" about it a week or so ago, and it has been officially announced. Singapore Airlines will launch a new, direct, same (wide body) plane service from Singapore to Wellington i, September, via Canberra. It will apparently be the first international flight to/from Canberra International Airport, and the first direct, same plane service from Wellington to Asia.
Flights will be operated 4 times a week, and times look great, allowing Wellingtonians (or anyone from around the centre of the Country really) to connect to it since it leave around 8:15pm. Word across the Tasman have also suggested that with a 23:00 departure from Canberra to Singapore, some people from Sydney may even be interested to connect to it to get ti Singapore the next morning, ready for a full day of business/activities, given that SIA doesn't offer any late (evening/night) flights from Sydney to Singapore.
I for one will be excited to see a Singapore Airlines Boeing 777 at Welly airport. :)
