The feature event on the calendar of the Gunnedah Greyhound Club, named in honour of their favourite son, champion chaser Chief Havoc.

The Cup has been won three times in recent years by Northern Rivers' trainer Garry Streatfield.

Streatfield won the 2013 and 2014 Chief Havoc Cup Finals when his grand campaigner Glenreagh Rocket won back to back titles, coincidentally the last on grass, and the first on sand at the Gunnedah track.

In 2019, Glenreagh Skud, who is the son of El Grand Senor and Magic Diore - who was runner-up to Glenreagh Rocket in the 2014 Cup - won the Cup again for Streatfield.

In 2021 the Robert Ayres-trained Lucky Lance was clearly the quickest in the heats and showed the form was no fluke when, he came from off the pace and in one of the most thrilling finishes in Cup history, he got the nod just in time, in an amazing four-way photo.

Young gun Jay Opetaia claimed the race in 2023 with Street Of Dreams who was the third elect wen the boxes opened.

It was a monstrous run from the Central West-based chaser after jumping from Box 8 and being forced to run three and four wide for most of the trip. He eventually overpowered longtime leader Red Hot Frankie in the shadows of the post to claim a deserved feature final win.

In 2024, Cindy Keeping won the event for Charmaine Roberts and Shayne Stiff.
