The Hawera-Muller NZMCA Park is an exclusive campground for New Zealand Motor Caravan Association members, situated near Nowell's Lakes just south of Hāwera in the South Taranaki region.

The park sits alongside Nowell's Lakes, a pair of pristine freshwater lakes formed within the coastal sand dune belt. Both lakes are ground-fed and support a variety of fish.

The surrounding area features the Nowell's Lakes Walkway, a moderate, well-signposted trail network beginning off Rifle Range Road.

The walks wind through a gully and farmland replanted in native trees, with seats, picnic tables, and a lakeside toilet available along the way. Between February and April, the area is notable for large numbers of Monarch butterflies and swan plants.

A secondary walk leads toward the coast.
