Smaller electricity retailers and generators are worried impending power market reforms won't create the level playing-field promised. 

The Electricity Authority's proposed a non-discrimination rule that will force gentailers to play fair when deciding to sell electricity to itself or other companies. 

Some smaller players, including Electric Kiwi, have written to the authority saying the rule doesn't go far enough. 

Its Chief Executive Huia Burt told Ryan Bridge the rule only applies to leftover electricity. 

But she says that could be a very insignificant amount of the total volume - which doesn't create a level playing field.
