This follows public engagement in 2018 and early 2019 on improving the whitebait management to restore populations and provide for a sustainable whitebait fishery.
The engagement included a DoC survey, where 90 per cent of respondents said changes were needed to make New Zealand's whitebait fishery sustainable.
DoC freshwater scientist Jane Goodman said whitebait were iconic in New Zealand.
"Unfortunately, four of the six whitebait species are categorised as either threatened or at risk of extinction. We need to ensure we protect their habitat, especially spawning areas," she said.
"It's good to see work being done to protect and restore whitebait habitat, such as planting and fencing off spawning grounds from stock and the restoration of adult habitat."
Whitebait need to be able to move between freshwater and marine habitats to complete their lifecycle. People should contact their local DoC or Regional Council office if they see overhanging culverts or other barriers that stop whitebait migrating.
"People can also help by fishing for whitebait responsibly and sustainably," Jane Goodman says.
Whitebait are juveniles of six species of native fish: giant kokopu, banded kokopu, shortjaw kokopu, inanga, koaro and common smelt. Those that escape the whitebait net grow into adults ranging from 10 to 60 centimetres long.
Everyone will get the opportunity to have their say during the public consultation. Information on this can be found on DoC's website.
