The Auckland City Council has recently authorized the Auckland ’s Strategic Transport Network 2042 however, although the political rational for creating the “Super City” which stretches from latitude 36.11S to latitude 37.29S was alleged to involve a necessity to increase transportation inefficiencies by eliminating the original individual constituent mini-cities, nothing much seems to have changed as the result of the enormous political shift that has resulted.

A rural area to the north of the metropolitan center exceeding 23,745 ha now forms part of the expanded city with a similar area of more than 11,966 ha to the south. The geographical capacity to support further north-south transmission arteries, particularly by road is severely constrained by the very narrow isthmus (2.0 km) at Otahuhu along with the six bridges and/or causeways. The time has clearly past us by wherein it was possible to sensibly think of further developing Auckland as a single, longitudinal North-South entity. At this stage of the game the focus of further development should changer to an east-west profile separately to the north and south of the latitude defined by the position of Otahuhu.

That said, we find that the super-city strategic road-works plan amounts to nothing more than the cobbled-together aspirations of the mini-cities it displaced together with the systematic development of in-fill housing on the northern and southern margins of the central metropolitan area.

Such systematic north-south oriented expansion of in-fill housing means nothing less than a progressive increase in north-south travel demand to the point where the super-city will choke itself.

At this point all we can hope to achieve that will make any sensible difference to the quality of life inside the burdensome overlay of cemented infrastructure across the central isthmus is to lay an ecological corridor from north to south to try to bring life back into the city proper and at the same time shift all new roading proposals into an east-west orientation.

Hence, in the support of life, we must project a biodiversity corridor north from Redoubt Ridge across the narrow isthmus to unite The Hunua Ranges in the south with the Waitakere wild-lands in the North-west. This will have the added advantage of protecting and enhancing the ancient north-south sacred Maori Walkway.
