Liam James Coltman (born 25 January 1990) is a New Zealand rugby union player who plays as a hooker for Lyon in Frances's domestic competition Top 14.
Born and raised in New Plymouth on the west coast of New Zealand's North Island, Coltman was educated at Francis Douglas Memorial College in his hometown, where he played first XV rugby.
He spent a large part of the 2016 Mitre 10 Cup season training with the All Blacks so was only able to feature in 4 matches for the Razorbacks as they topped the Championship log and made it all the way to the playoff final before being surprisingly defeated at home by North Harbour.
This apprenticeship served him well as Hore's retirement at the end of 2013 left Coltman as the Highlanders first choice hooker for 2014 Super Rugby season and he started 11 times as his franchise reached the tournament quarter finals before being defeated 31-27 by the Sharks in Durban.
[11][12] He was called up to the All Blacks squad to provide injury cover for Nathan Harris during the 2016 Rugby Championship, but didn't get any game time during the tournament as Dane Coles and Codie Taylor remained fit and in good form.
[13][14] Coltman failed to make the field for the All Blacks during 2017, due to injury, but was re-selected for the three-test 2018 Steinlager series against France after an outstanding Super Rugby season.
