Fishing is restricted to the face of the dam indicated by signs. Anglers may note enter the water unless they are wearing clean gumboots or waders. Fish must be taken whole from the site: no gutting or cleaning of fish is permitted anywhere on the site.

A Water Access Permit is required. It is available at no cost by self-help from the fishing kiosks at the reservoirs.

Access Travelling south from Auckland, turn off SH1 onto SH2. Then take a series of left turns, first into Mangatangi Road, then Kaiaua Road and finally Workman Road. See Mangatangi reservoir access map.
Methods Fly fishing using a nymph is generally most productive. retrieve the nymph slowly, giving it just an occasional twitch. As the water can be deep in the areas open to anglers long leaders are essential
Recommended tackle A long mono-filament leader, 3-5 m long, with a floating fly line. When nymph fishing try to get the flies down so a longer leader may be needed.
Recommended lures

Dry flies: During the days there can be mayfly hatches so flies such as Adams are useful to have on hand. In early to mid summer there are also good caddis (sedge) hatches in the late evening.

Nymphs: Pheasant tail and other similar patterns.

Wet flies: Woolly Buggers in green and black; small wet flies such as spiders retrieved slowly in the evenings. 

Spinners: Small bladed spinners such as Veltic or Mepps. During the summer soft baits are good alternatives.
