Despite freezing power prices for customers in Christchurch and Wellington, Contact Energy has no immediate plans to offer the same deal in Otago.
The company announced last week customers' bills in those areas would remain the same until the end of October next year.
Communications manager Jonathan Hill said the company reviewed prices regularly, on a regional basis.
However, the company had no plans to introduce a similar incentive in Otago, nor were price increases expected soon.
"The market is very competitive at the moment and we are responding to that," he said.
Mr Hill said "feedback seems to be overwhelmingly positive" about the price freeze and other discount offers the company had introduced, as opposed to the public backlash Contact experienced when it raised power prices in September.
Energy Minister Gerry Brownlee said Contact's move was "welcome" and it was clearly trying to increase its customer base.
However, he also encouraged consumers to shop around to ensure they were receiving the best deal for their money and hoped they were "becoming more conscious" about different companies' pricing structures.
