Zille raised the issue of red tape with Zuma at a meeting in August at which he agreed to follow up on her submissions.
More than 70 suggestions for amendments have been made by the provincial treasury and another nine departments.
"These include calls for national planning legislation to be simplified to avoid excessive delays to projects like housing and basic services," Zille said at a press conference.
"In some cases, up to four different laws require four different public participation processes for one project."
Zille cited the example of successive impact assessments, which took three years to complete.
"If the public participation processes could be dealt with at the same time, we could save two and a half years."
Zille said her submission for legislative change also raised the question of ports, which were "controlled by Transnet but not always run in a manner that benefits regional economics and communities".
Other suggestions by the DA leader include the amending of the SA Schools Act of 1996 to provide for random search and drug seizures at schools by professionals instead of by over-burdened principals.
It was suggested that relieving principals of this task would contribute to better performances at schools.
