Boil-up traditionally is a broth made from a balanced combination of meat and pork bones, bacon bones, lamb chops, or any type of meat, with greens such as pūhā, watercress or cabbage, and kūmara, spuds, boiled together, along with flour dumplings known as "doughboys".

The Ngaru Toa 'Raised On Boil Up' Tee is inspired by a lifelong tradition honored by all kiwis that has been past down from whanau to whanau to enjoy at gatherings and community get togethers.
