New Zealand has one of the highest skin cancer rates in the world. Over 90,000 non-melanoma skin cancers and around 2,800 invasive melanomas are diagnosed here each year. With numbers like those, regular skin checks aren't optional. They're one of the smartest things you can do for your health.
But how often should you actually go? The answer depends on your individual risk.
The General Recommendation
For most New Zealanders, an annual skin check is a sensible baseline. Our UV levels are significantly higher than countries at similar latitudes in the Northern Hemisphere, thanks to our thinner ozone layer and long summers spent outdoors. Even if you wear sunscreen and cover up, cumulative sun exposure builds over a lifetime.
A yearly check gives your doctor the chance to spot changes early, when treatment is simplest and outcomes are best.
When You Might Need Checks More Often
Some people benefit from skin checks every six months, or even more frequently. You fall into a higher-risk category if you:
- Have fair skin that burns easily
- Have a history of sunburn, particularly blistering sunburns in childhood
- Have many moles (50 or more) or moles that are large or irregular
- Have a personal or family history of melanoma or other skin cancers
- Work outdoors or spend significant time in the sun
- Have had organ transplants or take immunosuppressive medications
- Have a history of using tanning beds
If any of these apply to you, talk to your doctor about a more frequent schedule. Your GP can help you figure out the right interval based on your specific situation.
What Happens During a Mole Check and Skin Examination?
A thorough skin check (sometimes called a mole check) involves a full-body examination using dermatoscopy, a specialised magnifying technique that lets your doctor see structures beneath the skin's surface. This is painless and non-invasive. Your doctor will look at moles, freckles, and any spots that have changed in size, shape, or colour.
The whole process typically takes 15 to 30 minutes, depending on how many spots need close attention.
Why Early Detection Matters
Melanoma caught at its earliest stage has a five-year survival rate above 95%. Left unchecked, it can spread to lymph nodes and other organs, where treatment becomes far more complex. The same principle applies to basal cell carcinomas and squamous cell carcinomas. Caught early, they're usually straightforward to treat. Left alone, they can cause significant tissue damage and require more extensive surgery.
A regular skin check is a small investment of time that can make a serious difference.
Don't Wait for Something to Look Wrong
Many skin cancers don't match the dramatic images you see online. They can be subtle: a small scaly patch, a pimple that won't heal, a mole that's shifted colour slightly. Trained eyes pick up what untrained ones miss.
If it's been more than a year since your last check (or if you've never had one), now is a good time to book.
At Wellspring Skin in Taupō, Dr Natalie Clarke and Dr Vanda Nobre are both credentialed with the New Zealand Skin Cancer and Dermatoscopy Society. They offer thorough skin assessments using dermatoscopy, and if anything needs treatment, diagnosis and surgery happen in-house. Skin checks are open to everyone, not only enrolled patients.
