KEY POINTS:
Napier's iconic Marineland has just one dolphin left and looks set for closure following a vote tonight.
Napier City Council is likely to say the attraction should shut down when the last-surviving dolphin, 38-year-old Kelly, dies.
Marineland will probably then be transformed into a marine hospital and education centre.
More than 13,500 signatories had called on the Government to fund the replacement of the dolphins.
But in May Parliament's local government and environment select committee rejected the petition.
Kelly has been a Marineland feature since December 1974. She has been the only performing dolphin since 36-year-old Shona died in April 2006.
It is hoped she will still be on show next summer.
Hundreds of thousands of holidaymakers have visited since the attraction opened in January 1965.
