Haywards


Haywards is a small hillside suburb in the Hutt Valley near Wellington, New Zealand. It is notable for its large electrical substation, which is the main switching point for the Wellington region, and the home of the North Island converter station for the HVDC Inter-Island, which links the North and South Island electricity networks together.

Suburbs and towns near Haywards include Belmont, Judgeford, Silverstream, Trentham and Taita.

State Highway 58 is the primary route from the Hutt Valley to Pauatahanui and Porirua. It leaves State Highway 2 at Haywards. This highway was first built during the 1870s. From the 1940s to the 1970s there were proposals for a railway line, the Haywards–Plimmerton Line, via this route.

In June 2010, the results of a road assessment programme indicated that the Haywards Hill road was amongst the worst in the Wellington region, scoring only 2 out a possible 5. The NZ Transport Agency has proposed a project for the creation of an elevated interchange at the intersection of SH2 and SH58 at Haywards, including a new carpark and the replacement of an existing underpass with a footbridge across SH2 to Manor Park.

The Haywards electrical substation is one of national grid operator Transpower's largest substations and is a key part of New Zealand's national electricity network. The North Island converter station for the HVDC Inter-Island is co-sited with the main HVAC substation, and converts the ±350 kV direct current electricity transmitted from the South Island converter station at Benmore to 220 kV alternating current for the North Island, and vice versa.
