What we collect
When you contact us
If you send an enquiry through our website, email or phone us, we collect your name, email address, phone number (if you give it) and anything you tell us about yourself, your site or your project.
When we work with you
When you are a client, or are involved in a project as a consultant, contractor, supplier or council officer, we collect business contact details and the information needed to deliver the project. This can include information about properties and sites, and about the people connected with them, such as owners or occupiers.
When you apply for a job
If you apply for a role, we collect the information you send us: your CV, cover letter, contact details, qualifications and work history. With your agreement, we may also contact your referees and carry out other pre-employment checks. We will tell you about these and ask for your consent before we do them.
When you visit our website
Our website and the services built into it automatically collect technical information. This includes your IP address, browser and device type, the pages you view, how you arrived at our site and your approximate location. Much of this is collected through cookies (see "Cookies and similar technologies" below).
We don't ask for sensitive information, such as health details, through our website. Please don't include it in an enquiry unless it's relevant to your project.
Information we collect from other people
Sometimes we collect information about you from someone else. Examples include a client who gives us your details as a project contact or neighbour, referees you have nominated, councils, Land Information New Zealand and other public records, and our project partners.
How we use your information
We use personal information to:
• respond to enquiries and prepare fee proposals
• deliver our engineering services, run projects and work with councils and other project parties
• invoice and manage our client and supplier relationships
• assess job applications and recruit staff
• keep our website secure and protect our contact form from spam
• understand how our website is used and measure our online advertising
• meet our legal, professional and regulatory obligations.
We don't send marketing emails and we don't sell personal information. We only use it for other purposes if you agree or the law allows it.
Cookies and similar technologies
Cookies are small files stored on your device when you visit a website. We use the following:
• Squarespace, our website platform, uses essential cookies to run the site securely and to give us basic, aggregated visitor statistics.
• Google Ads conversion tracking and remarketing, managed through Google Tag Manager. These tell us when someone who clicked one of our ads goes on to contact us, and let Google show ACH ads to people who have visited our website.
• The LinkedIn Insight Tag gives us aggregated, anonymous information about our website visitors, such as industry and job function. It also measures and targets our LinkedIn advertising.
• Google reCAPTCHA protects our contact form from spam. It collects information about your device and how you interact with the page, and sends it to Google.
• Google Maps shows our office location on the Contact page.
You can block or delete cookies in your browser settings, although parts of the site, such as the contact form, may not work without them. You can control the ads you see from Google at https://myadcenter.google.com and from LinkedIn at https://www.linkedin.com/psettings/advertising.
Google and LinkedIn handle the information they collect under their own privacy policies: https://policies.google.com/privacy and https://www.linkedin.com/legal/privacy-policy.
Who we share your information with
We only share personal information when we need to. This may be with:
• ACH staff who need it to do their work
• service providers who host, store or process information for us, including Squarespace (website and contact form), Microsoft (email and document storage), Google and LinkedIn
• subconsultants, contractors, councils and other parties involved in your project, where needed to deliver it
• our professional advisers, insurers and auditors
• anyone else, where you have agreed or the law requires or allows it.
Storage, security and overseas providers
We store personal information on secure systems and take reasonable steps to protect it from loss, misuse and unauthorised access. Some of our service providers store information overseas, including in the United States and Australia. Where they hold it only to provide services to us, we remain responsible for it under New Zealand law.
If a privacy breach causes, or is likely to cause, serious harm, we will notify the people affected and the Office of the Privacy Commissioner, as the Privacy Act requires.
How long we keep it
We keep personal information only for as long as we need it for the purpose we collected it for, or as the law requires. Engineering project records are kept for many years after a project is complete, because of our obligations under building and professional liability law.
Your rights
You have the right to ask for the personal information we hold about you and to ask us to correct it. Email us at info@achconsulting.co.nz. We may need to confirm your identity first. We will respond as soon as we can, and within 20 working days. There is normally no charge.
If you have a concern about how we have handled your information, please contact us first so we can try to resolve it. If you are not satisfied, you can complain to the Office of the Privacy Commissioner at https://www.privacy.org.nz.
Links to other websites
Our website links to other sites, such as LinkedIn and Google Maps. We are not responsible for how those sites handle your information, so please check their privacy policies.
Changes to this policy
We may update this policy from time to time. The current version will always be on our website, with the date it was last updated.
