What was reported
Dai Henwood, one of New Zealand's best-known comedians, has died. He was 48.
1News reported on November 10, 2026, that he died that morning at Auckland Hospital. His management shared the news in a statement. "Nothing made Dai happier than making people laugh," it said.
1News said he had metastatic bowel cancer. Bowel cancer is the name used in New Zealand, Australia and the UK for colorectal cancer, which is cancer of the colon or rectum. He kept his illness private for nearly three years before he spoke about it in January 2023.
A life in comedy
He won the Billy T Award in 2002. He was a founding member of the panel show 7 Days. He also hosted Dancing with the Stars NZ and LEGO Masters NZ. In 2025 he was made an Officer of the New Zealand Order of Merit, for entertainment and charity fundraising.
He talked openly about his treatment. In April 2026 he said his 51st round of chemotherapy was his hardest yet. 1News said he also had major surgeries and a targeted drug called cetuximab.
He leaves his wife, Jo, and children Charlie and Lucy.
What was not reported
His management did not share details of his last months of care. This article does not guess at them.
Bowel cancer in brief
The colon and rectum make up the large intestine, the last part of the digestive system. Most colorectal cancers begin as a polyp, a small growth on the inner lining. Some polyps turn into cancer slowly, over years.
"Metastatic" means the cancer has spread to other parts of the body. NCI calls this stage IV colon cancer. NCI says cetuximab is approved to treat colorectal cancer that has spread to other parts of the body. It is used for some tumors, based on tests of the tumor's genes.

Not only an older person's cancer
He was in his early 40s when he was diagnosed. That is younger than many people expect.
NCI reports that colorectal cancer is a leading cause of cancer death in people under 50 in the United States. It says rates in adults younger than 50 have been rising steadily since the 1990s. Rates in older adults have dropped.
Signs worth checking
NCI says to check with your doctor if you have:
- Blood in the stool, either bright red or very dark.
- A change in bowel habits. NCI's examples are diarrhea, constipation, narrower stools, or feeling that you have not fully emptied your bowel.
- General belly discomfort, such as frequent gas pains, bloating, fullness or cramps.
- Weight loss for no known reason.
- Fatigue.
- Vomiting.
Other, more common problems can cause these too. Age is not a reason to ignore them. More detail is in colorectal cancer signs and symptoms.
When to see a doctor
Do not wait for blood in the stool or a lasting change in bowel habits to go away on its own. Make an appointment with your doctor and say what you have noticed.
A lot of blood in the stool, or black, tarry stool, can be an emergency. Our guide is rectal bleeding a sign of cancer? explains when to call 911 and when to call your doctor the same day.
Screening
In the United States, the USPSTF recommends colorectal cancer screening for adults aged 45 to 75. It recommends that doctors offer it selectively at ages 76 to 85. Screening is for people with no symptoms. It can find polyps before they turn into cancer.
People with a parent, brother, sister or child who had colorectal cancer may need to start earlier. Ask your doctor. Read more in colorectal cancer screening now starts at 45.
Screening ages differ by country. Readers outside the United States can ask their doctor about their national program.

Put the story in context
Prevention, possible warning signs, screening, and diagnosis
This story relates to Colorectal (bowel) cancer. The information below is general: it does not reveal anything else about a public person’s health, and not every point applies to every cancer. Personal advice depends on age, symptoms, family history, exposures, and medical history.
Prevention and risk reduction
Not every cancer can be prevented. Avoiding tobacco, protecting skin from ultraviolet radiation, limiting alcohol, staying active, and receiving recommended HPV or hepatitis B vaccination can lower the risk of certain cancers. A risk factor is not a prediction or a cause in one individual.
Symptoms and possible early signs
Possible signs vary and are often caused by conditions other than cancer. Changes worth discussing include a new lump, unexplained bleeding or weight loss, a persistent cough, lasting bowel or bladder changes, a changing skin spot, or symptoms that persist or worsen. Some early cancers cause no symptoms.
Screening and early detection
Screening looks for certain cancers before symptoms begin. Recommended tests exist only for some cancers and depend on age and risk. Screening can have benefits and harms; it is not the same as evaluating a new symptom, and there is no single routine scan or blood test that reliably screens for every cancer.
How cancer is diagnosed
Diagnosis may involve a history and exam, imaging, laboratory tests, and often a biopsy. Pathology can identify the cancer type and may test biomarkers that guide treatment. Symptoms, screening results, tumor markers, or online stories alone cannot confirm cancer.
