NZ DNS Settings & Email Configuration
.co.nz DNS settings are the specific configuration records—such as A, MX, CNAME, and TXT—that direct internet traffic for New Zealand domain names to the correct web servers and email providers. Correctly configuring these settings within your registrar’s zone editor is critical for ensuring website availability and reliable email delivery for NZ businesses.
For New Zealand digital asset managers, brokerages, and businesses, maintaining impeccable online infrastructure is not just a technical requirement—it is a matter of trust and operational continuity. The Domain Name System (DNS) acts as the phonebook of the internet, and for those operating under the .co.nz suffix, understanding how to manipulate these records is essential.

What are the Core DNS Records for .co.nz Domains?
When you purchase a domain through a registrar (such as 1st Domains, Crazy Domains, or SiteHost), you are given access to a DNS Zone Editor. This is the control panel where you define where your domain points. For a .co.nz domain, the propagation of these changes usually occurs rapidly, often within the local NZ network first.
To manage your digital assets effectively, you must understand the four pillars of DNS configuration:
1. A Records (Address Records)
The A Record is the primary pointer. It maps your domain name (e.g., yourbusiness.co.nz) to the specific IP address (IPv4) of the server hosting your website. Without an A Record, users typing your URL will face a connection error.
- Host: Usually entered as “@” or blank to represent the root domain.
- Value: A numerical IP address (e.g., 192.0.2.1).
- TTL (Time To Live): Determines how long servers cache the information. Lower values are better during migrations.
2. CNAME Records (Canonical Name)
A CNAME Record maps one domain name to another domain name. It does not point to an IP address. In the NZ market, this is frequently used to map the “www” version of your site to the non-www version, or to point subdomains to third-party services like Shopify or Squarespace.
- Host: “www” or a subdomain like “shop”.
- Value: The destination domain (e.g., yourbusiness.co.nz or shops.myshopify.com).
3. MX Records (Mail Exchange)
MX Records are arguably the most critical for business communication. They tell the internet which mail server accepts email for your domain. If you are a brokerage firm, a misconfigured MX record means lost client instructions and potential financial liability.
- Priority: A number indicating preference (e.g., 0, 10, 20). Lower numbers are tried first.
- Value: The address of the mail server (e.g., smtp.google.com).
4. TXT Records (Text)
Originally intended for human-readable notes, TXT Records are now the backbone of email security and domain verification. You will use these to prove you own the domain to Google/Microsoft and to set up SPF records to prevent email spoofing.

How to Configure Email for Google Workspace and Microsoft 365
Most New Zealand businesses utilize either Google Workspace or Microsoft 365. Setting these up requires precise modification of your .co.nz DNS settings. Before beginning, ensure you have administrative access to your domain registrar.
Setting up Google Workspace (formerly G Suite)
Google has simplified its architecture. While you used to need five different MX records, you can now often use a single record, though many legacy setups still use the multiple-record approach for redundancy.
The Primary MX Record:
- Type: MX
- Host/Name: @ (or leave blank)
- Priority: 1
- Destination/Value: ASPMX.L.GOOGLE.COM
If your registrar requires more, Google provides backup servers (ALT1 through ALT4) with priorities of 5 and 10. Do not forget to delete any pre-existing MX records pointing to your web host (like cPanel default mail), or your emails will bounce.
Setting up Microsoft 365 (Exchange Online)
Microsoft 365 requires a slightly more complex setup involving three distinct record types: MX, CNAME, and TXT.
- MX Record: Points email to Outlook.
- Priority: 0
- Value: domain-co-nz.mail.protection.outlook.com (Note: Microsoft replaces dots with hyphens in the domain part).
- CNAME (Autodiscover): Essential for configuring desktop Outlook clients and mobile devices automatically.
- Host: autodiscover
- Value: autodiscover.outlook.com
- TXT (SPF): Validates your emails.
- Value: v=spf1 include:spf.protection.outlook.com -all
Why is my email not receiving after launching a new website?
This is the most common panic point for NZ business owners. You launch a beautiful new website, update your DNS, and suddenly, your external email stops working. This usually happens because the DNS records were reset or overwritten during the website migration.
The “Local Delivery” Conflict
If your website is hosted on a cPanel server (common with many NZ hosts), the server often defaults to “Local Mail Exchanger.” This means the web server thinks it is responsible for your email. When a contact form on your site tries to send an email to info@yourdomain.co.nz, the server looks internally, doesn’t find the mailbox (because your email is actually at Microsoft/Google), and the email vanishes or bounces.
The Fix:
Log into your web hosting control panel (cPanel), find “Email Routing” or “MX Entry,” and change the setting from “Local” to “Remote Mail Exchanger.” This forces the web server to look at the public DNS records to find your actual email provider.
Propagation Delays
DNS changes are not instant. They propagate across the internet. For .co.nz domains, this is often fast (1-4 hours), but global propagation can take up to 48 hours. If you have a high TTL (Time To Live) set on your old records (e.g., 86400 seconds), other servers will cache the old location for 24 hours.
Strategy: Lower your TTL to 300 seconds (5 minutes) at least 24 hours before you plan to make major changes.

Advanced Security: SPF, DKIM, and DMARC
For the “NZ Digital Asset Management & Brokerage” niche, security is paramount. Basic DNS setup allows email flow, but it does not prevent identity theft. You must implement the following authentication protocols in your DNS.
SPF (Sender Policy Framework)
SPF is a TXT record that lists exactly which IP addresses and services are allowed to send email on your behalf. If you use Xero for invoicing and HubSpot for marketing, they must be included in your SPF record, or your emails will land in spam folders.
DKIM (DomainKeys Identified Mail)
DKIM adds a digital signature to your emails. You generate a key in your email admin panel (Google/Microsoft) and add it as a TXT record in your DNS. This proves the email was not altered in transit.
DMARC (Domain-based Message Authentication, Reporting, and Conformance)
DMARC ties SPF and DKIM together. It tells receiving servers what to do if an email fails validation (e.g., Reject it or Quarantine it). For financial institutions in NZ, a strict DMARC policy (p=reject) is industry standard to prevent phishing.
Local Support vs. Budget Registrar Support
When managing .co.nz domains, the choice of registrar impacts your ability to resolve DNS crises. While international giants like GoDaddy or Namecheap offer lower upfront costs, there are distinct advantages to using NZ-based registrars like SiteHost, 1st Domains, or Metaname.
Time Zone and Jurisdiction
If your DNS crashes at 2:00 PM NZST, waiting for US-based support to come online can cost you a day of trading. NZ-based registrars operate on New Zealand time. Furthermore, they are directly accredited by the Domain Name Commission (DNC), ensuring they adhere to local dispute resolution policies and consumer laws.
Latency and Infrastructure
While DNS is a global system, using local nameservers can provide marginal gains in lookup speeds for local traffic. More importantly, local hosts understand the specific peering arrangements within New Zealand ISPs, often resulting in more reliable routing for domestic customers.

People Also Ask
How long does it take for .co.nz DNS to propagate?
Typically, .co.nz DNS changes propagate within 1 to 4 hours due to the efficiency of the .nz registry. However, global propagation can take up to 24-48 hours depending on the TTL (Time To Live) settings configured on your records prior to the change.
Can I manage DNS settings without hosting a website?
Yes. You can purchase a domain name and manage its DNS records (Zone File) purely for email purposes (e.g., Office 365) without paying for website hosting. Most registrars provide “DNS Management” or “Zone Manager” services for free or a nominal fee.
What is the difference between a Registrar and a DNS Host?
A Registrar is where you buy the domain name (e.g., 1st Domains). A DNS Host is the server that holds your record file (Zone file). Often these are the same company, but you can buy a domain at one registrar and point the “Nameservers” to a different provider (like Cloudflare) to manage the DNS there.
How do I point my .co.nz domain to Shopify?
To point a .co.nz domain to Shopify, you typically need to change two records: Set the A Record (@) to Shopify’s IP address (23.227.38.65) and set the CNAME Record (www) to shops.myshopify.com.
Why are my emails going to spam after changing DNS?
This usually happens because the SPF and DKIM records were not copied over or configured correctly in the new DNS setup. Without these authentication records, receiving servers (like Gmail or Outlook) cannot verify your identity and may mark your messages as spam.
Is it better to use Cloudflare for NZ DNS?
Cloudflare is an excellent option for NZ businesses because they have data centers in Auckland, Wellington, and Christchurch. This ensures extremely fast DNS resolution times for local users and provides added security layers (DDoS protection) that standard registrars may not offer.
