Hooker Nathan Harris has extended his contract with the Chiefs for two more years.

The determined 23-year-old spent the 2015 Investec Super Rugby campaign on the sidelines after suffering an ankle injury during the All Blacks' historic match in Chicago.

During that time, and despite the setbacks, Harris showed plenty of heart to work his way back to full fitness.

Chiefs coach Dave Rennie has hailed Nathan as a team player with exactly the right attitude needed to succeed.

'He is very diligent, eager to learn and we expect him to continue where he left off with his on-field performance,” says Dave.

Harris will return to the action today when his ITM Cup team, the Bay of Plenty Steamers, play the Manawatu Turbos in a pre-season fixture at Tauranga's Domain.

The former New Zealand Under-20 international is looking forward to getting some much-needed game time under his belt.

'I have spent the best part of nine months rehabilitating,” explains Nathan, 'so I am amped and ready to get stuck in.

'The Chiefs is a fantastic environment and they were extremely supportive last season.

'It's a great culture to learn in, so I am keen to get back on the paddock and put my best foot forward for them.”

Harris has played 12 games for the Chiefs, making his unusual debut against the Crusaders in Round one in 2014 where, due to multiple injuries, he went on at flanker, marking Richie McCaw.
