At Riverland Park, adjacent to the Dublin St bridge, owner Michael Wilson said he had received a phone call from the council to pack up his go karts, boats, mini golf equipment and workshop tools and get out.

Other rivers in the area also rose rapidly, including the Whangaehu, Waitotara and Mangawhero.
The Waitotara River peaked at 10m and residents in the Waitotara township were warned to be prepared for flooding.
The Matarawa Stream, which runs through Wanganui East, was rising yesterday afternoon at a rate of half a metre per hour and was being sandbagged around the Matarawa Stream bridge.

At midday yesterday Pipiriki locals Josephine and Ken Howarth said Whanganui River was already at 12m, and still rising visibly.
The Pipiriki tour operators said this would be the highest they've seen the river in 10 years. "The river is still rising, but we're okay up here."
Mrs Howarth said the water would probably not reach the lowest houses in the village that were at the entrance to the road leading down to the river.
