On camera, My Kitchen Rules New Zealand rivals the "Modern Day Hippies" and the "Corporate Dads" are locked in a tense battle for a $100,000 winners' cheque.
But off camera, the duos have united behind gravely ill Hamilton woman Angela Sunkel, who is battling a deadly form of cancer.
The 30-year-old suffers from chronic myelomonocytic leukemia and has been undergoing chemotherapy for almost two years. But now the only option is getting a stem-cell transplant in America, which comes with a $1.3 million price tag.
Waikato residents have rallied around Sunkel, including Cambridge-based Neena Truscott and Belinda MacDonald - MKR's Modern Day Hippies.
Along with the show's Corporate Dads - Auckland mates Josh King and Aaron Gascoigne - they sold their cooking skills to the highest bidder in online auctions held this week.
