Consumer Discounts

Network Tasman has been crediting network charge discounts onto consumers’ power bills since 1994. To find out whether you are within Network Tasman's coverage area click here.

Network Tasman is a consumer-owned electricity distributor

The company has been providing network discounts to its consumers since 1994. The amount of discount each consumer receives depends on their electricity usage. The discounts appear as a credit on eligible consumers’ power accounts.


The next discount provided by Network Tasman will be credited on the power bill you receive from your electricity retailers in either September or October 2018. It will be based on your electricity usage from 1 April 2018 to 31 August 2018.

A further discount will be credited on to power bills in either April or May 2019. That discount will be based on electricity usage from 1 September 2018 to 31 March 2019.

In previous years discounts have been provided in July/August and November/December. In the context of a revised interpretation by the IRD of tax treatment of discounts, Network Tasman now posts its network discounts on its network pricing schedule and this has necessitated a change in the timing of its discounts. This will ensure that there is no change in the tax treatment of discounts, so that the overall discount amount will remain the same as the previous year.


To be eligible for a line charge discount a consumer must have an active, metered connection to the network as at midnight on a specific day. These days are announced each year via print advertisements and on the Network Tasman website.


Any of the following circumstances will exclude a consumer from receiving 
the discount: 

  • The meters have been removed prior to midnight on the respective cut-off dates
  • The consumer’s connection has been disconnected or is vacant or inactive on
the registry prior to the respective cut-off dates
  • The consumer’s connection has temporary boxes or unmetered connections such as streetlights or electric fences
  • The consumer has had a final reading or requested a final reading to be taken on or before midnight on the respective cut-off date.

Discount Calculation

Discounts are calculated at a set rate per kilowatt hour (kWh) of consumers’ total consumption.

The discount rate for 2018/19 is 2.99 c/kWh (including GST) for residential consumers, and most business and commercial consumers. Network Tasman will calculate your next discount using consumption (kWh) from 1 April 2018 to 31 August 2018.  This data is provided by your electricity retailer, using meter readings at your connection (ICP).

Discounts will vary between consumers because of consumers' different levels of electricity consumption.  An average residential consumer will receive a discount of $97 (including GST) in September or October 2018 and discount of $106 (including GST) in April or May 2019. The total discount of $203 (including GST) is the same as what was provided in previous years for the same electricity consumption level.
