Noticed a changing mole, persistent rash or unusual spot on your skin? One of the first questions you may have is whether to book an appointment with your GP, visit a skin cancer clinic or see a dermatologist.
In New Zealand, all three can play an important role in diagnosing and managing skin concerns. However, the right choice depends on your symptoms, medical history and the type of care you need.
At Skin Centre in Tauranga, our specialist dermatologists diagnose and treat a wide range of skin conditions and skin cancers. In this guide, we explain the differences between these healthcare options and when specialist assessment may be appropriate.
What’s the Difference Between a GP, Skin Cancer Clinic and Dermatologist?
A GP is often the first point of contact for skin concerns. GPs can assess common rashes, infections, acne and suspicious spots, prescribe treatments and refer patients for further investigation when needed.
A skin cancer clinic focuses on examining skin lesions and identifying possible skin cancers. The qualifications and experience of practitioners vary between clinics, so it’s worth checking who will perform your examination.
A dermatologist is a medical specialist trained to diagnose and manage diseases affecting the skin, hair and nails. Dermatologists assess complex or persistent skin conditions and can also provide specialist skin cancer diagnosis and treatment.
The most appropriate practitioner depends on your particular concern.
When Should You See a GP for a Skin Problem?
Your GP is a sensible starting point for many common skin complaints, including mild eczema, acne, fungal infections, minor rashes and skin irritation.
A GP can examine your skin, recommend treatment and assess whether further investigation is necessary.
You may benefit from specialist dermatology assessment if your symptoms persist despite treatment, repeatedly return, are difficult to diagnose or significantly affect your daily life.
A suspicious or changing skin lesion should be assessed promptly rather than waiting for a routine appointment.
When Should You Visit a Skin Cancer Clinic?
A skin cancer clinic may be appropriate if you’re concerned about a mole, have a history of sun exposure or want your skin examined for potentially cancerous lesions.
During a skin examination, a trained clinician may use a dermatoscope, which magnifies skin structures and helps identify features that cannot easily be seen with the naked eye.
Depending on your individual risk, the clinician may recommend further investigation, monitoring, a biopsy or treatment.
It’s important to understand that a skin check and mole mapping are not the same thing.
A skin check involves examining your skin for concerning lesions. Mole mapping uses photography and imaging to record selected moles or larger areas of skin so changes can be assessed over time.
Not everyone needs mole mapping. Your clinician can advise whether it would be useful based on your skin cancer risk and examination findings.
When Should You See a Dermatologist?
A dermatologist may be particularly helpful when a skin condition is complex, persistent, recurrent or requires specialist treatment.
Common reasons for seeing a dermatologist include:
• Eczema that remains troublesome despite treatment
• Moderate or severe psoriasis
• Persistent acne or acne scarring
• Rosacea and ongoing facial redness
• Unexplained or recurring rashes
• Suspicious or difficult-to-assess skin lesions
• Skin cancers requiring specialist management
Dermatologists can distinguish between conditions that may appear similar but require different treatments.
For example, facial redness could be associated with rosacea, dermatitis or another skin disorder. An accurate diagnosis is important before starting treatment.
Can a Dermatologist Check for Skin Cancer?
Yes. Dermatologists are trained to recognise and assess suspicious skin lesions, including melanoma, basal cell carcinoma and squamous cell carcinoma.
A dermatologist may examine the skin using dermoscopy and recommend a biopsy if a lesion needs further investigation.
Treatment depends on the diagnosis, location, size and characteristics of the lesion, as well as the patient’s individual circumstances.
Some skin cancers can be treated with standard surgical excision, while selected cases may benefit from specialised approaches such as Mohs micrographic surgery.
At Skin Centre, our team provides skin cancer assessment and specialist treatment, including surgical management where appropriate.
What Are the Warning Signs of Skin Cancer?
Skin cancers don’t always look the same. Some appear as changing moles, while others develop as persistent sores, scaly patches or unusual lumps.
Signs worth having assessed include:
• A mole that changes in size, shape or colour
• A new or unusual-looking pigmented spot
• A sore that doesn’t heal
• A lesion that repeatedly bleeds or crusts
• A growing, tender or scaly lump
• A spot that looks noticeably different from your other moles
The ABCDE guide — Asymmetry, Border, Colour, Diameter and Evolving — can help people recognise some warning signs of melanoma.
However, not all melanomas follow these patterns, and some are not darkly pigmented.
If you notice a new, changing or concerning skin lesion, arrange a professional assessment rather than relying on photographs or an online diagnosis.
Do You Need a GP Referral to See a Dermatologist in New Zealand?
Referral requirements depend on the clinic and whether you’re seeking public or private care.
Public dermatology services generally require a referral and are subject to local eligibility and prioritisation criteria.
Some private dermatology clinics accept direct appointments, while others may request a GP referral or relevant medical information.
Before booking, ask your chosen clinic about its referral requirements, consultation fees and expected appointment availability.
Is a Dermatologist Better Than a GP for Skin Conditions?
Not necessarily. GPs and dermatologists have different but complementary roles.
A GP is well placed to manage many everyday skin problems. A dermatologist provides additional specialist expertise when diagnosis is uncertain, symptoms are persistent or more advanced treatment is required.
For many patients, the best approach begins with a GP and progresses to specialist care when clinically appropriate.
If you’re worried about a suspicious lesion, the priority is a timely assessment by an appropriately trained healthcare professional.
What Happens During a Dermatologist Appointment?
A dermatologist consultation generally begins with a discussion about your symptoms, medical history, previous treatments and concerns.
Your dermatologist may then:
• Examine the affected skin
• Use dermoscopy or other examination techniques
• Discuss possible diagnoses
• Recommend further testing or a biopsy if necessary
• Explain treatment options and follow-up requirements
Some conditions can be diagnosed during the consultation, while others require additional investigations.
At Skin Centre, we develop individual treatment plans based on each patient’s diagnosis and circumstances.

Frequently Asked Questions
Should I see a dermatologist for a changing mole?
A changing mole should be assessed promptly by an appropriately trained healthcare professional. Depending on the findings, specialist dermatology assessment or further investigation may be recommended.
Can a GP diagnose skin cancer?
GPs can assess suspicious skin lesions, and some have additional training in dermoscopy and skin cancer diagnosis. If a lesion is uncertain or requires specialist management, referral may be appropriate. A biopsy may be needed to confirm the diagnosis.
Is mole mapping better than a normal skin check?
Neither is automatically better. A clinical skin examination assesses the skin for concerning lesions, while mole mapping can help monitor changes over time in selected patients. Your clinician can advise whether additional imaging is useful.
What skin conditions do dermatologists treat?
Dermatologists diagnose and manage conditions including eczema, psoriasis, acne, rosacea, skin infections, inflammatory disorders and skin cancer.

Yes. Private dermatology services are available in New Zealand, although booking and referral requirements vary between providers.
