Company Profile 1.1.1 Overview Unison Networks Limited (Unison) is an energy infrastructure business based in the North Island of New Zealand. Unison and its subsidiaries have a range of interests, products and service offerings including electricity distribution, communications, distribution equipment, facility management services, renewable generation development, and energy infrastructure contracting services. 1.1.2 Corporate Goals Unison’s key corporate goals are published in its Statement of Corporate Intent and have been reproduced below. These goals are critically relevant to the way Unison manages its asset base. Vision “To be the service provider of choice for energy infrastructure solutions” Mission “To be a successful business through excellence in customer service, innovation, and leadership” 1.1.3 Ownership and Governance Unison is wholly owned by the Hawke’s Bay Power Consumers’ Trust (HBPCT) on behalf of Hawke’s Bay electricity consumers. Unison’s Board of Directors is appointed by the HBPCT. 1.1.4 Electricity Distribution Network Electricity distribution businesses (EDB) are an integral part of New Zealand’s electricity market, forming the physical link between the transmission network and electricity consumers. Unison owns, manages and operates the distribution network that serves Hawke’s Bay, Rotorua and Taupo consumers. Electricity supply is taken at 33kV from Transpower’s grid exit points (GXP) and is transported to zone substations by Unison’s sub-transmission network. At zone substations, the voltage is converted to 11kV for distribution. Over 9,000 distribution substations throughout the network then reduce the voltage to 400V for end use. This Asset Management Plan (AMP) is concerned with the management of the assets that deliver this service. The Unison network is comprised of over $420m worth of assets, almost 10,000km in length and supplies around 110,000 connection points, making Unison the fifth largest EDB in New Zealand. Within Unison’s network footprint are a variety of terrain types and consumer densities, meaning it is necessary to employ a range of reticulation methods and asset management techniques to strike the optimal balance between quality of supply and efficient deployment of assets. The quality of supply experienced by Unison’s consumers has improved consistently over the past five years. SECTION 1 SUMMARY OF THE PLAN 1-3 The following table provides further information on the Unison network according to key industry metrics. Metric Description Value (2009/10) Trend Consumers Total installation control points (ICP) connected to the network. 108,212 connected System length Total length of all energised circuits. 9,571km Sub-transmission Total length of all energised 33kV circuits. 441km system length Distribution system Total length of all energised 11kV circuits. 4,561km length Low voltage system Total length of all energised LV circuits. 4,569km length Percentage The proportion of total system length that is undergrounded. 39% - underground Asset value Unison’s Regulatory Asset Base. $429m Faults per 100km Average number of unplanned interruptions per 100km of high 6.2 voltage circuits per annum.

  • Brown Bullhead Catfish (Ameiurus Nebulosus) in Lake Taupo
    Brown bullhead catfish (Ameiurus nebulosus) in Lake Taupo Grant E. Barnes1 and Brendan J. Hicks2 1Environment Waikato, P.O. Box 4010, Hamilton, New Zealand. [email protected] 2Centre for Biodiversity and Ecology Research, Department of Biological Sciences, University of Waikato, Private Bag 3105, Hamilton, New Zealand. [email protected] ABSTRACT Brown bullhead catfish (Ameiurus nebulosus) were first discovered in Lake Taupo during the early 1980s and are believed to have originated from an illegal liberation into the southern end of the lake. A native of the southern and eastern states of America, these catfish have been in New Zealand since 1878 and are now widespread throughout the Waikato region. In 1995 the population structure, abundance, age, growth rate and diet of catfish in the littoral zone (<5 m deep) of Lake Taupo were examined by setting fyke nets overnight in three different habitat types. A total of 6247 catfish was caught from 269 fyke-net sets (mean CPUE 23 fish net–1 night–1). Catfish abundance was greatest in shallow, sheltered, macrophyte-dominated bays, where the population was skewed towards small catfish (<150 mm FL). Adjacent rocky headlands and escarpments supported populations of large fish (>150 mm FL) and small fish. Low numbers of catfish across all size classes were caught from exposed sandy sites. The diet of catfish was size and habitat dependent. Small catfish (<150 mm FL) fed predominantly on chironomids, Cladocera, gastropods, caddisfly larvae, plant material and detritus. Larger catfish were found to prey to a greater extent on koura (Paranephrops planifrons), fish and terrestrial invertebrates.
