There are only three Waikato/Bay of Plenty teams left in the cup competition including Melville United, Tauranga City United and Ngongotaha.
Ngongotaha are the lowest ranked side left in the competition but will be high on confidence going into their clash with Melville, who knocked them out of the cup competition last year with a 2-1 victory in Hamilton.
Melville United play in the Northern League First Division, the same competition as Hibiscus Coast, and made the semifinals of the Chatham Cup last year.
Only one Rotorua side has ever made the final of the Chatham Cup in the competition's 91-year history. Rotorua City made the final in 1989, losing to Christchurch United 7-1.
