The CRL will quite literally be a game-changer.
Given the CRL's importance to Auckland's social, commercial and economic health, it's appropriate that public transport and investment in transport infrastructure are issues attracting attention in the mayoral debates.
The candidates are right that there are a large range of diverse challenges facing Tāmaki Makaurau and many of those are centred around population growth, with Auckland forecast to top two million people by 2033. How are they all going to get around?
Other questions, which I'm sure the candidates also want answers to, is how do we make Auckland an international city of the same standing as Barcelona or Vancouver, and how do we grow the city in a way we all will be proud of in 30 years' time?
Sydney and Melbourne have faced and then surmounted these same issues Auckland faces. Melbourne, in particular, is an instructive case study for Tāmaki Makaurau.
In the 1990s, Melbourne was a rust-bucket city with its manufacturing base emptying out and significant numbers of people leaving for Queensland. Their civic leaders did a whole range of things, including the creation of pedestrian-friendly streets and walker-only lanes (it's worth pointing out that when Auckland Council made Fort St in the CBD a shared space for pedestrians, hospitality spending increased 429 per cent).
But the most important change in Melbourne was ensuring public transport underpinned all the other innovations around the city.
By the time of the 2006 Commonwealth Games, you could catch a tram, bus or walk to 90 per cent of all sporting events. International media took notice, with The Economist putting Melbourne on a par with Vienna and Vancouver.
As Melbourne has continued to grow and car congestion has continued to increase, Melbourne is taking more and more steps to be a public transport lead city. Many young people in the inner city no longer own a car as they simply don't need to to get around.
The Melbourne CBD is now basically given over to (free) CBD trams and cycleways.
Melbournians now think nothing of catching public transport to theatre and sports events in the evening and the weekend. It is a much easier option.
Effective and efficient public transport is the great enabler of great cities. It accelerates investment across the commercial and social economies, bolsters the arts, events, retail and hospitality sectors and creates new businesses and new jobs.
Highly effective, efficient, accessible public transport is a key enabler in any "international standard" city and the CRL will be the catalyst for that important change in Auckland.
The CRL is now nearing the end of its tunnel construction phase and we will this year begin fitting out the tunnels with a vast array of equipment and materials, including 16km of rail and more than 1.5 million metres of cable.
It is possibly the biggest fit-out of a project in New Zealand construction history. It is a fit-out for Auckland's future and we will soon literally see the light at the end of the tunnel, which is exciting for all Aucklanders.
