New Zealand derbies are a highlight on any player's calendar but Andy Ellis has particular reason to relish the next few weeks.
Beginning with the Highlanders tomorrow night, the Crusaders face Kiwi opposition for four games in a row, an important period for the veteran halfback.
Ellis makes no secret of his desire to once again pull on the black jersey and, throughout the rest of the month, he will have the chance to test himself against those in the All Black frame.
First, it's incumbent Aaron Smith at AMI Stadium tomorrow, before the Chiefs and two-test halfback Augustine Pulu come to town, followed by a visit to TJ Perenara and the Hurricanes.
The encounters will be crucial on a team level, considering the congested nature of the New Zealand conference, and the individual battles may be equally pivotal.
