Former Leinster head coach and Australia rugby global Matt O'Connor will once again take charge at English Premiership side Leicester Tigers.
The Australian won three Premiership titles in his previous spell at Welford Road and will begin his new role in April after recently being assistant coach with the Tonga national team.
Former New Zealand star centre Mauger stepped up from the head coach position - which he had assumed when O'Connor left in 2013 - after long-serving director of rugby and Tigers icon Richard Cockerill was sacked as director of rugby on January 2.
Leicester chairman Peter Tom said: 'The club have conducted an exhaustive search to find who we feel is the right person to take the team forward.
"And this brought up the names of a number of potentially very good coaches".
Former All Black Aaron Mauger will coach English Premiership club Leicester for one more game before an unceremonious exit.
"Matt has that experience as head coach during a successful period which brought three league titles, an Anglo-Welsh Cup and the club's most recent appearance in the European Cup final. The team also topped the try-scoring figures in the Premiership four times in that five-year period with Matt in charge of the attack".
The timing of the appointment is peculiar, with the Tigers now fighting for a place in the Premiership semi-finals while they also ended their four-year trophy drought yesterday with victory in the Anglo-Welsh Cup final over Exeter.
His first campaign saw him win the 2013-14 Pro 12 title, beating Glasgow Warriors in the final.
"Matt's strengths are in his work with players on the training pitch and we are making changes to our organisational structure to enable him to focus exclusively on the success of the team".
Leicester are now fifth in the Premiership, one point behind Bath with five regular-season games remaining.
"We wish him well for the future".
