For the 2006 NBL season, the Rams brought in new American coach Chris Sparks and a shooting guard Dennis Trammell from the United States.
On 28 April 2006, Kench scored a career high of 30 points, while dishing out 5 assists, in a loss to the Auckland Stars at Cowles Stadium, in Christchurch.
Kench's strong play continued on in the second half of the season where on 9 June 2006, he had another outstanding game posting 27 points in a victory over the Otago Nuggets in Dunedin.
His strong play in 2006 was rewarded on 11 May 2006 when he was selected in the New Zealand Tall Blacks squad to prepare for the 2006 Basketball World Championship in Japan.
As a consequence of the Canterbury earthquake in February 2011, the Cougars disbanded and Kench was forced to find another team to play for in the 2011 NBL season, subsequently joining the Manawatu Jets.
[3] On 14 December 2015, Kench retired from elite basketball, confessing his heart was no longer in the sport, calling it quits after 12 years in the New Zealand NBL and 194 games.
