A group of scientists are digging to the bottom of a hangi pit to find out why the Earth's magnetic field has changed over the centuries - which is important to navigation.
 
Scientists, archaeologists and Te Kawa a Maui, the School of Maori Studies at Victoria University, have teamed up in a unique project to investigate changes in the Earth's magnetic field through the magnetisation of ancient hangi stones.
