NZ Respiratory & Sleep Institute
NZRSI provides lung function and sleep laboratory testing.  We also have a group of 10 Respiratory & Sleep Specialists along with two Sleep & Respiratory Paediatricians who provide consulting services.  We are centrally located with parking on-site.  We provide the country's best and most comprehensive private respiratory and sleep service. 

Respiratory & Sleep Specialists are able to provide clinical consultation for patients with respiratory disease and sleep disorders, including snoring.  Urgent consultation (same day) is available, by arrangement, for patients with cancer or abnormal radiology.

The specialists also undertake timely consultation and investigations to meet immigration and occupational requirements. There is particular expertise in occupational lung disease, diving and aviation (altitude) medicine.

Sleep & Breathing (NZ) Ltd is able to undertake a full range of diagnostic lung function testing, from simple spirometry to more detailed pulmonary physiology testing.  We also now provide TB induced sputum testing. 

We provide the best range of sleep testing in Australasia; in-lab polysomnography and MSLT/MWT, home based sleep apnoea assessments; prolonged infraRed video monitoring and actigraphy.

Sleep & Breathing (NZ) Ltd provides a full range of equipment for people with sleep or lung disorders needing treatment with nasal CPAP and oral devices.  We provide a full range of light therapy (White lightboxes and Green lightboxes) devices for the management of seasonal affective disorder (SAD) and circadian disorders. 

Psychologist Kimberley Falconer has a particular interest in working with sleep disorders. She draws on research and experience to help patients make simple changes designed to restore sleep.

We also have three Respiratory Physiotherapists, Sarah Mooney, Sarah Butler and Trina Robertson.  Sarah Mooney has worked extensively in her chosen field and has an interest in the management of bronchiectasis and breathing pattern disorders.  More recently, she has undertaken research in different aspects of both respiratory conditions. Sarah Butler has specialised in respiratory paediatric care since 1992. She specialises in the treatment of children and young people with breathing disorders including those with cystic fibrosis, asthma, bronchiectasis and breathing pattern dysfunction.  Trina Robertson sees people with a wide variety of respiratory presentations, including COPD, bronchiectasis, interstitial lung disease and disordered breathing.

Our Dietitian, Amy Liu, specialises in weight management, diabetes (type 1 and type 2), high cholesterol, managing acute kidney failure, polycystic ovarian syndrome, eating disorders, sports nutrition, pregnancy and lactation, gastrointestinal disorders, allergies and elimination diet.  

Sleep & Breathing (NZ) Ltd has a Clinical Research Division which is actively involved in drug and equipment research.


What is Respiratory Medicine?
Respiratory medicine is the branch of medicine that investigates and treats people with diseases affecting the lungs, breathing tubes, chest wall and breathing.

Common symptoms or signs of lung disease include: shortness of breath, wheezing, cough, coughing up blood or sputum (phlegm), and having chest pains.

The lungs deliver oxygen into our bloodstream and remove carbon dioxide.  When you breathe in, air passes through the throat into the windpipe (trachea). The base of the windpipe divides into the right and left tubes (bronchi) which divide again and again each time getting smaller and smaller like the branches of a tree, until the smallest airways deliver the air to the alveoli. The alveoli are the spongy spaces where oxygen and carbon dioxide are exchanged.  They act like balloons i.e. when you breathe in they inflate and when you breathe out they relax.

Oxygen moves across the walls of the alveoli and enters the bloodstream and is carried to the rest of the body after passing through the heart. Carbon dioxide is passed from the blood into the alveoli and is breathed out of the lungs.


What is Sleep Medicine?
Sleep medicine is the specialty which investigates and manages disorders where there is difficulty in getting off to sleep or staying awake in the night (insomnias), difficulty with feeling tired or sleepy in the day (sleep apnoea, narcolepsy, restless leg syndrome, snoring etc), and with the movement disorders of sleep (parasomnias such as sleep walking and talking, REM behaviour disorder, nocturnal epilepsies).

We provide the best range of sleep testing in Australasia; in-lab polysomnography and MSLT/MWT, home based sleep apnoea assessments; prolonged infraRed video monitoring and actigraphy.

A range of treatments are coordinated for the management of snoring and sleep apnoea by the Institute, including pressure treatment with nasal CPAP, dental devices and upper airway surgery.  Light boxes of various types correct seasonal affective disorder (SAD) and circadian problems with sleep timing.  We have access to a range of medication and experts in the non drug treatment of insomnia.

Referral Expectations

Your GP will refer you to us if they are concerned about your lungs or breathing, or if they think you may have a sleep disorder and require a specialist opinion. Sometimes they may refer you directly for a test which will be seen and reported by a specialist.
Recommendations and options regarding your diagnosis and treatment plan will be discussed with you and a letter will be sent to your GP.
You need to bring to your appointment:
1. Any letters or reports from your doctor or another hospital
2. Any X-rays, CT (computer tomography) or MRI (magnetic resonance imaging) films and reports.  It is best to ask your radiologist to give you a disk with all your X-rays and scans on it.  We can load this into our computers for long term storage
3. A list of all medicines you are currently taking, including herbal and natural remedies.

If you have any change in your condition before you come to your appointment, please see your GP immediately.

Sleep & Breathing (NZ) Ltd is a Southern Cross Affiliated Provider, with agreed charges for lung function and sleep investigations. 

When we see you, we may ask whether you wish to be included on a research database which would allow us to contact you for research studies in the future.  You are not obliged to consent for inclusion in the database and this would not affect your treatment in any way.  Inclusion in the database would allow us to contact you about a study in the future which you may wish to take part in, but consent for each study would be sought separately.

  • Peak Flow Meter

    This is a small hand-held tube that can measure what is happening in your breathing tubes.  You can have one at home and measure your peak flow by blowing into it as hard and fast as possible.  You will be shown how to measure it and compare it with what… More

  • Blood Gas Tests

    This is similar to a blood test but instead of a needle going into a vein it is inserted briefly into a small artery in your wrist.  A small amount of blood is taken and sent to the laboratory for information about the oxygenation of your blood and other gases.… More

  • Chest X-ray

    A chest X-ray is normally undertaken to check the chest wall, lungs and heart.… More

    With CT you can see much more detail than with a normal X-ray.… More

  • Fine Needle Aspirate

    Depending on what is seen on the CT scan an additional test can be done where a fine needle is inserted into your chest into the cancer and some cells sucked up into the needle.  This is done while taking pictures with the CT scanner to guide the doctor as… More

  • Bronchoscopy

    During this test a thin fibreoptic tube is inserted into your breathing tubes, through the nose, to view the tubes and take a biopsy (remove cells or tissue) to see if there are cancer cells present.… More
