"The last time we had a whale stranding in the Bay of Plenty was Nobby,'' about three years ago, said DOC's Katrina Knill.
"Gray's beaked whales are relatively rare but do appear in Tauranga Harbour from time to time.''
DOC said it won't be known whether this stranding was related to the Rena oil spill until the post mortem examination of the juvenile whale is completed.
