PORT NIKAU PORT NIKAU

The Port Nikau property is situated at the southern side of Whangarei, the main commercial centre of the Northland region of New Zealand, approximately 150 kilometres or two hours’ drive north of Auckland.

The Port Road area houses a wide range of industries, but there is a particular emphasis on marine industries, as some sites have direct access to the water. Ship builders, chandlers and repair yards are numerous. The McCrae’s ship repair facility, situated close to the property on Port Rd, has one of the largest slipways in the country. The local marine industry is currently in the planning phase, with Government support, for providing deepwater access to and from water for large vessels.

The Ex-Tenix property is located at the end of Lower Port Road, adjacent to the harbour edge. The land surrounding it was until recently the Port of Whangarei’s main operations area, prior to its relocation to Marsden Point south of the town.

The surrounding area lends itself to comprehensive redevelopment, and some commentators are suggesting that in time the area could house not only other industrial uses, but residential, and perhaps commercial or educational facilities.

Whangarei is the business centre of Northland, a city of 50,000 people just two hours’ drive from Auckland.

The underground piped stream/stormwater is diverted into Waitangi Park. Water is harvested upstream of Cable Street via a weir mechanism. Wind or solar powered pumps bring the water just below the surface of the activity zone, where heavy particulates are settled out and grease scum are skimmed. Between 10-15 L/s of water is diverted into a 6.0 meter wide linear wetland system. Particulate pollutants are removed from the water as it passes through the densely planted native sedges and reeds. Water permeates into the gravelly subgrade where bio-organisms remove suspended pollutants. Plants help maintain the porosity of the filtering medium. Series of thickly planted sloped terraces that provides a further polishing process as the water moves down slope towards the harbour into a large open air pond. Shallow planted ledges and deeper open bodies of water are visually captivating. The pond stores enough water for re-use in site-wide irrigation and water features. Water discharges at the Waka Landing and Clyde Quay terminations of the linear wetlands. Tree planting along the streetside promenade, in addition to framing this generously wide pedestrian way, incorporates bio-retention/fitration features. Stormwater runoff from the parkside of the road and the promenade itself is directed into treepits through either a series of kerb slots or dish drains. Water collects within the sunken planted tree pits then slowly filters through the soil medium where contaminants are removed by micro-organisms inhabiting the root zone.

Barangaroo is located on the western edge of Sydney’s CBD, on the shores of Sydney’s world famous harbour. It is currently 22 hectares of disused container wharves.

When complete, Barangaroo will showcase how city populations can live sustainably. It will create a new, 21st century western face to our city. It will include six hectares of a new headland park, busy public waterfront walks and parks, commercial office towers and apartments, all serviced by new and extended transport systems.

The site has been divided into three redevelopment areas - the Headland Park, Barangaroo Central and Barangaroo South.

Plan to generate more renewable energy than used at Barangaroo, recycle and export more water than used and reuse, reduce and recycle more waste from the city than generated at Barangaroo.

Plan to be carbon neutral, water positive, generate zero waste and enhance the wellbeing of the community.

Plan to provide affordable housing for key workers as well as green skilling and local employment opportunities. Just over 50 percent of Barangaroo will be dedicated public space, including a 2.2 kilometre foreshore walk and the vibrant, naturalistic Headland Park.
