Eels? Sure, but marlin on the Hikurangi swamp?
That's exactly what Hikurangi swamp dairy farmer Geoff Crawford discovered when he went to open a floodgate to release floodwaters about 8am today.
He discovered one dead marlin was stuck in the floodgate and three others were floating, partly submerged about 2km away.
The bodies of the four marlin were intact except the beaks had been removed. Mr Crawford said the marlin had been dumped and he was shocked to make the find.
"It's shocking. What does it take for people to dig a hole and bury them?" he said.
