"I had had long covid for 3 years before I started on this programme. I was very apprehensive and a little scared to start with. Hamish was very kind and patient with me. He set it all up and showed me how to use it correctly and only a phone call away if I needed anything. It was nice to have it at home and not have to go out each day. I stuck with a routine of using it mid morning each day for 90min. I was concerned I wouldn't remember the instructions as my memory was terrible and my brain was very foggy but it's all written out and very easy to follow. I added an extra mattress and pillows for extra comfort. I could sit up or lay down in the cocoon I had. I watched movies and TV on my phone for the 90min each day. It was very relaxing. I felt the oxygen cocoon work for me on the third day of using it! I couldn't believe it. My head was clearer, I could think properly, it was truly amazing. I had finally found my miracle. I would highly recommend this programme to anyone that has long covid. Give it a try. It worked for me."
"Our son had concussion for a long time and we could not find anyone to help until we were referred to Dr Gary. He was wonderful with our son and we really appreciated how much he cares for his patients and wants to see them get better. The hyperbaric chamber worked wonders and our son made rapid progress in recovering from his concussions which was life changing. We got our happy bubbly little boy back and he is now back in school full time and able to do all of the activities he loves. Dr Gary was very accomodating and we found we were always able to contact him for advice. Highly recommend this business."
"I can absolutely recommend Cocoon if you are thinking of renting or buying a hyperbaric chamber. I had dealings with several companies before deciding on Cocoon, and I can say that the enquiry experience was far superior in every way with Cocoon. Doctors Loraine and Gary Denis are extremely helpful, knowledgable and truly care about their clients and patients. I opted for a full Neurocare program with Dr Gary after years of chronic undiagnosed illness, along with the rental of a chamber, and it has been an absolute game changer for my health. Not only has the program and support set me well on the road to recovery, the whole team (including Caroline the Account Manager) showed support, compassion, flexibility and gave me complete confidence that I would be able to heal. If you are hiring or buying an HBOT, I really recommend hiring from health professionals who can advise you correctly and I am confident you will be pleased you chose Cocoon."
Why we exist
Cocoon exists because Gary needed it himself.
"In 2019, a serious brain injury changed everything. I started mild hyperbaric oxygen therapy and within weeks could feel it working — but the travel and cost of daily clinic visits quickly became a burden. Everything I researched said HBOT only works done daily, without breaks. So I set up a chamber at home: the routine became easy, my results improved, and it cost far less. That's why I built Cocoon — I lived this, so we assess your situation, build a plan around it, and stay a phone call away."
Today, Cocoon helps people across New Zealand access guided at-home HBOT.

New to HBOT?
Why are more people exploring HBOT?
You may be hearing more about hyperbaric oxygen therapy lately. While HBOT has been used in clinical settings for decades, more people are now exploring it as a way to support recovery, brain health, energy and overall wellbeing.
Drug-free and non-invasive
A gentle therapy that works alongside the care you're already receiving.
Supported by decades of research
HBOT has been used in clinical settings for decades and continues to be studied across a wide range of applications.
Recovery fits into daily life
At-home HBOT removes the need for daily clinic visits, making consistency easier.
Personalised guidance matters
HBOT isn't one-size-fits-all. That's why every Cocoon programme is built around your goals and circumstances.
The difference
A chamber is equipment. Recovery is a programme.
Most people think HBOT is something you rent. But the chamber is only one part of the equation. The results come from having the right plan, doing it consistently, and having someone guide you along the way.
Just the equipment
A chamber, on its own
It's why so many people try a handful of sessions, feel little, and quietly decide HBOT "doesn't work" for them.
A guided path
The Cocoon Recovery Programme
The chamber is where it happens. The programme is what makes it happen.
You can rent a chamber almost anywhere. The programme around it is the part you can’t — and it’s the part that actually matters.
Why consistency matters
The hard part was never the chamber — it’s doing it every day
HBOT isn’t a one-off. It’s a course of regular sessions, usually done daily over several weeks — and doing it consistently is the part that matters. That’s exactly where a clinic makes life hard: getting there every single day is tiring and expensive. It was the wall Gary hit himself, and it’s why Cocoon brings the programme home.
Daily clinic visits
The usual way
Daily sessions at home
With Cocoon
HBOT is meant to be done consistently. Home is what makes consistency possible.
Why Cocoon
The difference isn’t the equipment. It’s the people behind it.
What makes the biggest difference isn’t the chamber itself. It’s the experience guiding the programme, the support behind it, and the people who help you stay on track.

Climb in, relax and let it run. Quiet, easy, and simple to fit into your day.
Your peace of mind
Gentle by design — and you’re never on your own
It’s natural to have questions about safety, especially when considering HBOT at home. That's why every programme begins with a suitability assessment, full setup and ongoing practitioner support.
Low-pressure & gentle
Our soft-shell chambers use mild, low-pressure HBOT — far gentler than the high-pressure chambers used in hospitals.
Assessed for suitability
Before you start, we check that HBOT is appropriate for you. It isn’t right for everyone — and if it’s not, we’ll tell you honestly.
Set up & shown how
We install everything and walk you through safe, confident use — right from your very first session.
Guided throughout
A registered practitioner oversees your programme and is only a message away whenever you need them.
