Skaters there need to be extremely cautious as Mahinerangi arm is a tricky place to skate - and dangerous if you are not prepared. It needs hard frosts and the ice changes rapidly as the lake is well exposed to wind and sun (the wind farm is nearby). The lake level constantly falls over the winter period and creates dangerous ice shelves around the edge - and these create thaw points for the wind. The lake edge can be very muddy if there is no hard frost.
