We collect information relating to you that:

3. To provide goods or services you have requested;

4. To improve those goods and services we provide you;

5. To maintain your shareholder information;

6. To bill you and to collect money that you owe us, including authorising and processing credit card transactions;

7. To respond to communications from you, including a complaint made by you;

8. To conduct research and statistical analysis (on an anonymised basis);

9. For recruitment purposes if you are applying for a job at MainPower.

10. Where you have expressly consented to us collecting and using that information, e.g. when you apply for an account with MainPower or enter a competition or promotion run by us;

11. As necessary to protect or enforce our legal rights or interests (including to protect our IT systems or to improve cyber security), or to defend any claims made against us by any person (including you); or

12. For any other purpose authorised by you or permitted by law.

Where possible, we will collect the information directly from you. We may collect your information via phone, written correspondence, email, our website, social networking websites or forms.

Personal information may also be gathered through third parties including your electricity retailer, electrical contractor or your representatives, market research service providers, social networking sites (such as Facebook, Twitter and Youtube), publicly available sources and from our transaction records.

CCTV Footage

We also use CCTV cameras to record footage at some of our sites for the purposes of ensuring the security of our sites and property. This footage may constitute ‘personal information' as defined in the Privacy Act, and by entering our monitored sites you acknowledge, and consent to, the collection of any footage.

Footage from the CCTV cameras can only be accessed by the GM Network Operations and the Infrastructure Manager in Network Operations. CCTV camera footage will be managed in accordance with our privacy policy.

Meter Data

We may collect meter data provided by your electricity retailer or metering equipment provider. This will be used either for network planning purposes or to help us assess the impact of pricing. Wherever possible we will agree a process with the data provider to aggregate the data so that you cannot be identified.

In the event that we use an independent third party to aggregate the data we will ensure that appropriate non-disclosure arrangements are in place.

We will hold meter data securely in accordance with best industry practice. Meter data will only be held for only as long as is necessary to achieve the purpose for which it has been collected, unless an exception applies, as required by the Privacy Act 2020.

4. Sharing your information

There may be times when we need to disclose your personal information to third parties. We will disclose your personal information only in accordance with this Policy and the Act. We may provide personal information to third parties where necessary or appropriate to facilitate the purpose for which information was collected pursuant to the Policy. You authorise us to disclose your information to:

1. Other parts of our company group who may use and disclose your information for the same purposes as us;

2. Those who provide us with products or services that support the services that we provide, such as (but not limited to) our suppliers, field service providers and contractors;

3. Credit reference agencies (unless we have agreed otherwise), who may share your information with other organisations and who may keep a record of the searches we make against your name;

4. Marketing, market research and website development and usage services. There are specific rules that govern the use of personal information for direct marketing. If your personal information is used for direct marketing purposes, we will always give you the choice to opt out of being part of any future direct marketing activities.

5. If someone else pays your bill, such as your landlord, that person;

6. Anyone we transfer our business to in respect of which you are a customer or a potential customer;

7. Anyone who hosts or maintains data centres, service platforms, cloud based solutions and other infrastructure and systems on behalf of MainPower, where your information is processed, hosted or stored; or,

8. Any person or organisation as authorised by the Privacy Act 2020. Otherwise, we will only disclose your personal information without your consent if doing so is:

9. The relevant authorities where necessary to protect or enforce our legal rights or interests, or to defend any claims made against us by any person (including you);

10. The relevant parties necessary in order to report a cyber incident or for cyber security purposes (including to prevent unauthorised access to, or attacks on, our systems);

11. To the relevant parties where necessary to lessen a serious threat to a person's health or safety; or,

12. Other persons, as required by law.

5. Security of your personal information

We will take all reasonable steps to ensure that the personal information we collect, use or disclose is accurate, complete, up to date and securely protected against loss, unauthorised access and other misuse. This includes physical security, computer and network security, communications security, and personnel security.

We may retain all personal information that we collect (on our active systems and our archive systems) only for as long as necessary to carry out the purposes for which the information was collected (including for the purpose of providing services to you). CCTV footage will usually be retained for a period of 15 days, after which time it will be deleted.

We may provide your personal information to third parties contracted by us in order to perform data storage and data processing services on our behalf. We will take all reasonable steps to ensure that these third parties comply with our instructions and do not use your personal information for any other purpose. We may store your personal information on servers and services both within New Zealand and offshore (including third party cloud-based services and storage). We may access and use that personal information in and outside New Zealand. You acknowledge that some of the third party storage providers, which provide services to us under contract, are based in other countries that may not have equivalent privacy and data protection laws to New Zealand.

6. Accessing and updating your personal information

You may request access to the personal information we hold about you by sending an email to Please quote your name and address. We would be grateful if you could also provide brief details of what information you want a copy of (this helps us to more readily locate your data). We may also need you to confirm your identity, before providing information to you.

In accordance with the Act, in some cases, there may be a charge associated with providing copies of your personal information to you. If so, we will advise you of this prior to sending your information to you.

We will not be able to provide your personal information if we do not know or don't have reasonable grounds to believe it is personal information about you or if disclosing the information would involve the unwarranted disclosure of the affairs of another individual.

You can request correction or amendment of the information held by us at any time and as often as necessary by sending us an email to and specifying the information that you require changed.

If it is reasonable in the circumstances for us to do so, we will make the requested change or correction, otherwise we'll take reasonable steps to mark that information as having been subject to a change or correction request.

This is to ensure that others cannot access your personal information and correspondence if you share a computer with someone else or are using a computer in a public place.

7. Internet use, including cookies

We make every effort to maintain the security of our internet connections; however, for reasons outside of our control, due to the public nature of the internet security risks may still arise.
