Almost 10,000 Tauranga customers changed their power company in the past 13 months - but the city's switching rate is below other major centres.
Figures released by the Electricity Authority show Tauranga customers switched energy providers 9225 times from May 2014 to May 2015.
The biggest changes were for Energy Online, which gained a net 288 customers, and Trustpower, which lost a net 862.
As of May 31, Trustpower had 73 per cent of the market share in Tauranga with 57,928 customers. The next largest is Genesis Energy, which holds 10 per cent of the market - 7729 customers.
Electricity Authority acting chief executive John Rampton said Tauranga electricity consumers have typically not been as active at shopping around as consumers in other parts of New Zealand and their switching rate remained below other major centres.
