Waikato could be left without a domestic rugby coach this season.
The BBC is reporting that the outgoing Ulster coach and incoming Waikato mentor Jono Gibbes has reportedly held talks with La Rochelle about taking charge of the French club.
The former All Black has already agreed to take charge of Waikato but could now remain in Europe instead.
The French Top 14 side say they hope to make an announcement in the near future.
Ulster, who granted Gibbes’ request for an early release from his contract for family reasons, will host Ospreys in a European play-off on Monday.
The winner will secure the seventh and final qualifying place from the Pro14 for the 2018-19 European Champions Cup.
Ulster could not comment on French media reports that Gibbes was being pursued by La Rochelle.
The former Leinster and Clermont Auvergne forwards coach flew to the west coast of France during a rest day for the Ulster squad.
The 41-year-old Gibbes, was promoted to the role of head coach at Kingspan Stadium in January following the departure of director of rugby Les Kiss and led the side to a four-match unbeaten run at the end of the regular season.
La Rochelle finished outside the play-off places in the Top14 table this season and are seeking a successor to Patrice Collazo, who stepped down after seven years in charge.
