Tilt Renewables locked in a more lucrative and final takeover deal with AGL Energy’s renewables fund and Mercury Energy at $NZ8.10 a share, after a last-ditch attempt by a Canadian pension fund to start a bidding war.

The pension fund, Caisse de depot et placement du Quebec (CDPQ), turned up with a late $NZ8 a share bid on Thursday, made one month after the auction, sparking Tilt’s sale momentarily back to life.
