Despite starting the first Test Kruis would play no other part in the Series as Alun Wyn Jones, Courtney Lawes and Maro Itoje kept Kruis out of the 23-man squad.
Yet Kruis was outstanding throughout, with his highlight of the Tour coming against the Crusaders when he won six lineouts against the Super Rugby side in Christchurch during a 12-3 victory for Gatland’s side.
The England international played 258 minutes during the entire Tour, winning 14 lineouts in the process and making 44 tackles.
