 Although it is no longer a forestry or dairy centre, the town is still a tourist attraction, largely because of its many historic buildings, the hot springs at Parakai and the Parakai Aerodrome, and its proximity to Auckland. It has also seen positive effects from the nearby wine producing region around Kumeu, 20 km to the south. There are also an increasing number of lifestyle blocks in the area.
 Helensville has its own locally produced monthly newspaper called the Helensville News.

 Parakai is noted for its hot springs with geothermal mineral water occurring naturally. There is a complex of mineral pools and recreational activities, such as Parakai Springs. These pools are fed from bores which draw from a geothermal aquifer which lies in the fractured Waitemata sandstone and compacted alluvial sediments.
 There is little recorded history of Māori using these springs, though it is to be assumed that they were known as the local iwi Ngāti Whatua had made use of the springs in the neighbouring Helensville.
 In 1864 Robert Mair "discovered" the hot springs, which at the time consisted of one natural hot pool. In 1905 a bore was sunk 20 metres and a year later a new bathhouse was built. This began twenty-five years of tourism and investment in the hot pools (and Parakai more widely) which, at its peak, included a Reserve which contained a Massage Institute, 24 private baths, and men's and women's swimming baths. The economic downturn of the Depression and onset of World War II caused visitor numbers to dwindle, and by 1958 two of the boarding houses had burned down, and the swimming baths were closed.
