Jim, you asked if we have a “rainy season” here in NZ. Winter is June,July and August, with colder days, and nights, more rain, and snow,mostly in the South Island, and the higher areas in the North Island. And yes, metal roads get slushy, muddy and slippery. In the busier areas, graders come to move the snow, or level the metal to make driving safer.photo courtesy on Internet.Models like this or similar, and many other brands and designs to suit all purposes.
Here is a road in Otago , in summer , the green grass looking good for the sheep.
A little further up the road, in the middle of winter, snowbound, even 4WD vehicles had problems, and tractor transport was safer.
Tractors of all brands and sizes, cabs with comfortable seats, necessary for the colder South Island winters. Photo courtesy of the Internet.
Many roads that go to the ski fields, or ones that have snow covering them in winter, have “chain bays”, where vehicles can pull over and fit chains on the wheels before carrying on. This is on a tar-sealed road from Arrowtown to Wanaka, South Island.
Another part of the same road, December 2011.
