Internationals Jerome Kaino, Patrick Tuipulotu, Ofa Tu'ungafasi and Male Sa'u return to the Blues line-up for Saturday's Super Rugby match against the Hurricanes in Wellington.
Kaino, Tu'ungafasi and Tuipulotu were involved with the All Blacks series against Wales and Sa'u played for Japan against Scotland.
They will be welcome additions to the Blues, who have lost All Blacks Charlie Faumuina and George Moala to injury.
There's a relatively settled look to the side with a forward pack built around five current or former All Blacks, with the backs built around the core inside trio of Bryn Hall, Ihaia West and Piers Francis.
Sa'u, who played on the wing for Japan in their international series at home, will return to his usual role of centre for the injured Moala.
