Limitations of the data
This dataset provides a handy indicator of how recent price increases are likely to impact on consumers. However, it does not reflect what customers have actually paid for electricity in any particular period, as the QSDEP only models one type of customer in each city or town, when in reality, Consumption and pricing plans vary significantly across households.
Lines prices cover both distribution and transmission services combined.
Prices assume that prompt payment discounts are claimed. They do not include multi-fuel and online discounts, incentive or retention payments, or rates paid by customers on fixed-term plans.
Prices do not include any ownership-based discounts and distributions from consumer trusts. If these discounts and distributions were included, the prices would be lower.

About this dataset
The QSDEP is a price indicator series that complements sales-based electricity cost data. The QSDEP indicator is a measure of how the published residential electricity tariffs have changed over time.
Method of collection/Data provider
A limited selection of publicly advertised retail tariffs are surveyed for around 40 towns and cities across New Zealand.
Prices are surveyed as a snapshot at the mid-point of each quarter (15 February, 15 May, 15 August and 15 November each year).
The average prices are quoted for a modelled consumer using around 22 kWh per day (8000 kWh of electricity per year).
An average regional price across all retailers is published, weighted by market share.
