We’ve released residential savings numbers and consumption data for 2017. In addition to this, we’ve also added a trend report for residential consumption that helps users observe changes in residential energy consumption through time and contrast these trends between regions. Check out the daily average residential consumption for each month over the last five years below.

Barriers to entry and exit impact market dynamics. Monitoring the entry and exit of firms in the retail market, therefore, enables insights to be drawn about these barriers, and market performance more generally. We've added a report that tracks entry and exit of parent companies, traders, and brands in the retail electricity market. The retail market has seen a significant number of new retailers begin operations, with 22 retail parent companies entering since the beginning of 2013 (and three exiting). This represents a net increase of 19 retailers, up 135 per cent on the 2013 numbers. Some of these companies are very small and may only operate locally, while others are challenging competitors across the whole country. Hover over the markers to see who entered or exited.

The market share trends report shows the growth (or decline) of the new entrant retailers. You may want to try zooming in to see what the smaller retailers are up to. The ability to scale retail operations rapidly is often dependent on investment in systems and processes, as well as the marketing effort. For information on how these entrants are helping create a more competitive market structure see our annual changes in market structure dashboard.

The number of connections (installations control points) in the retail market continues to increase. This means there are more consumers for retailers to compete to supply. Over time the share of connections supplied by small and medium retailers in aggregate is growing steadily. Take a look at the share in the North Island - small and medium retailers combined now serve more than Meridian or Trustpower.

This report provides an alternate view of consumer choice focusing on the changes that occur within a year. The West Coast region recorded a 70 per cent increase in maximum available choice, up from just 10 in 2016 to 17 in 2017.
