Rudd

Habitat Distribution

• Introduced from Eurasia — not native to New Zealand. First released into Waikato lakes and ponds in the late 1960s; now well established across much of the North Island, particularly in the Waikato River catchment.
• Scattered populations exist around Christchurch and in parts of the South Island's West Coast, spread through illegal releases over decades.
• Prefer still or slow-moving water: lakes, ponds, and weedy pools in streams and rivers. Dense aquatic vegetation is the key habitat feature.
• In the Bay of Plenty, historic sites such as Lake McLaren have been recorded, though recent surveys have not confirmed active populations there.

Key Locations

• Waikato River catchment and associated lakes — the heartland of New Zealand's rudd population and the main area where sport fishing for them is legal and actively pursued.
• Hamilton Lake (Lake Rotoroa) — a well-known coarse-fishing venue in the Waikato where rudd share water with tench and perch.
• Lakes and ponds around Auckland — rudd are widespread here, though fishing restrictions apply in high-conservation-value catchments within the region.
• Scattered populations around Christchurch and the South Island West Coast exist, but these are outside the sports-fish zone and subject to noxious-fish rules.

Specific Spots

• Weed edges and submerged vegetation are the primary holding areas — rudd feed heavily on aquatic plants and the invertebrates living among them.
• Shallow, warm bays in lakes concentrate fish during spring and summer when water temperatures rise and spawning activity begins.
• Tree roots and overhanging bankside vegetation attract fish looking for shade and food; eggs are also laid on these structures during the spawn.
• In rivers and streams, look for slow backwaters and weedy pools rather than open current — rudd avoid fast water.
