The Power Compare database of NZ power companies and NZ power plans is one of the most comprehensive in the country. We compare a huge range of power plans and power deals from over 30 different New Zealand power providers. From companies who offer power and broadband bundled plans to no contract power deals or power companies that suit a poor credit rating. Power companies offer a range of deals for new customers, from sign up bonuses to prompt payment discounts, we compare all the deals. In addition to sign up bonuses, there are often other, softer features to compare. These include which power company has the best customer service or the power provider who offers a loyalty scheme or predominantly green energy.
