Environment Canterbury concedes an oil spill near a marine reserve is not able to be contained. The 25-metre long Austro Carina crashed into the rocks and ran aground at Canterbury's Shell Bay on the eastern side of the peninsula on Sunday night.The four crew made it to shore and had to be winched out by helicopter. It is estimated 10,000 litres of diesel and 400 litres of hydraulic fluid is on the grounded ship. Aerial observations are set to get underway to work out the extent of the situation, but weather is limiting a containment operation. The spill is close to the Akaroa Marine Reserve and the area is home to protected species like the korora/little blue penguin and the upokohue/Hector's dolphins among several others. Kathryn speaks with Andy Thompson, DoC's Mahaanui operations manager and Shireen Helps owner and founder of Pohatu Penguins, a wildlife tour company on Banks Peninsula.

A global cancer trial that seeks to use a patient's own immune system to target and destroy melanomas is set to get underway in New Zealand. Aotearoa has the highest rates of melanoma - the most serious, and deadly skin cancer - in the world. Next month, recruitment begins for a clinical trial of an INT - Individualised Neoantigen Therapy. The therapy, used in combination with cancer drug Keytruda, is personalised to each patient, based on their tumour's unique genetic mutations. The Phase 3 clinical trial is recruiting patients who have had melanomas surgically removed, but are ineligible for the Pharmac funded Keytruda. Trial oncologist Gareth Rivalland speaks to Kathryn.
