Certified Short Marketing Courses: Are Certifications Actually Worth It?
Feb 06, 2026
Last updated: October 2026 · Written by 20 Minute Marketing · 8 min read
Marketing certifications are worth it only in specific circumstances. For career changers and agency employees, Google Ads and HubSpot certifications carry genuine professional value. For small business owners, the results your marketing produces matter far more than any certificate on your wall.
Only some certifications are worth it. For most New Zealand learners, practical skills come first: 20 Minute Marketing is paid once from $79 to $999 (Essentials is $499 for over 50 lessons), with 12 months access, a 30 day money-back guarantee and a Certificate of Completion. Add Google Skillshop's free foundational certifications alongside it.
20 Minute Marketing publishes this guide and ranks its own course first. Here is why, and where other options fit better.

The marketing education industry has created significant confusion around certifications. Most courses offer some form of “certificate” or “certification”, but these terms are not interchangeable, and most are worth considerably less than the premium you pay for them. This guide cuts through the noise.

Certifications That Actually Matter in New Zealand
Google Ads Certification ✓
Google’s own certification program is widely known to employers. Its foundational certifications are free; Google says its professional Google Ads certifications will require an exam fee in future (checked 3 October 2026). It requires passing an exam that tests genuine platform knowledge (not just course completion), which makes it more credible than most alternatives. If you manage Google Ads for clients or professionally, this is worth pursuing.
HubSpot Academy Certifications ✓
HubSpot’s free certifications in Inbound Marketing, Content Marketing, and Email Marketing are widely used, particularly in B2B marketing roles. The content is genuinely strong, free, and credible, which makes them valuable for career changers and professionals adding to their skillset. Note: most are global/US-focused, so they complement rather than replace Kiwi-specific training.
Google Analytics (GA4) Certification ✓
Free through Google Skillshop, the GA4 certification validates your ability to configure, report, and extract insight from Google Analytics 4. It is practically useful (GA4 is notoriously counterintuitive) and is useful to show employers and clients who know what it represents.
Should You Pursue a Certified Marketing Course? It Depends on Your Goal.
| Your Goal | Do Certifications Matter? | Best Approach |
|---|---|---|
| Career change into marketing | Yes: credibility signal for employers | Google Ads + HubSpot (free) + a strong portfolio |
| Freelance marketing services | Minimal: clients care about results | Results and case studies beat certificates |
| Small business owner marketing their own business | No: your results are the proof | Focus on practical, implementable skills |
| Employee seeking promotion | Sometimes: depends on employer | Industry-recognised only (Google, HubSpot) |
The Certification Premium: What You’re Actually Paying For
Certified courses often cost more than equivalent non-certified courses. What does that premium actually buy?
- An exam or assessment (sometimes; often just a quiz)
- A digital certificate for your LinkedIn profile
- Branding around “certification” in the course marketing
What it rarely buys: better instruction, better content, or better outcomes. The exception is the free industry-backed certifications (Google, HubSpot) where the credential itself has genuine professional value.

Is 20 Minute Marketing accredited?
No. 20 Minute Marketing is not a registered private training establishment, and its courses are not approved or accredited by NZQA. You receive a Certificate of Completion, which records that you finished a self-paced online course. If you need a recognised qualification, a polytechnic or another NZQA-approved provider is the right choice.
Are marketing certifications worth it for NZ small business owners?
For business owners marketing their own businesses, certifications have very limited practical value. Your results (more leads, higher conversions, better ROI from ads) matter far more than any certificate. The exception is the free platform certifications (Google Ads, GA4) which also teach genuinely useful skills in the process of earning them.
Which marketing certifications actually matter in New Zealand?
Google Ads Certification, Google Analytics (GA4) Certification, and HubSpot Academy certifications are the most practically valuable and widely known in New Zealand. Their foundational versions are free to study; Google says its professional Google Ads exams will require a fee in future (checked 3 October 2026). Generic “digital marketing certifications” from course providers without industry backing carry minimal professional weight.
Is a certified marketing course better than a non-certified one?
Not necessarily. Certification relates to credential issuance, not teaching quality. A non-certified course with strong practical content, Kiwi-specific examples, and implementation-focused structure will almost always produce better business outcomes than a certified course with generic theory. Focus on what you’ll learn and implement, not on the certificate you’ll receive.
How do I get a Google Ads Certification in New Zealand?
Visit Google Skillshop (skillshop.google.com), create a free account, and complete the Google Ads certification assessment for each product area (Search, Display, Video, Shopping). Certifications renew annually. Google says its professional Google Ads certification exams will require a fee in future, so check the current position on Skillshop before you start (checked 3 October 2026).
