Today, the underlying driver of urban issues is the problems that the administrative bodies of the cities and metropolises, such as municipalities, struggle with, and the failure in informing the public and clarifying performance, legality, consensus and collective wisdom of authorities, participation, etc., have undermined their performance. This research aims to elaborate on the status of good urban governance using the mixed method in the new city of Golbahar. To investigate the status of good governance dimensions in the new city of Golbahar, 385 questionnaires were distributed among citizens, 48 questionnaires were submitted to municipal and city council experts, and semi-structured interviews were conducted with 10 officials of the ​​new cities. Then, adopting a mixed approach, which merges quantitative (descriptive-analytical) and qualitative methods, the status of good urban governance indicators in Golbahar was evaluated. The results derived from the analysis of good urban governance indicators suggest that their average scores, with the exception of legality, transparency and strategic vision, were below average as reported by citizens (within the relative range of 2.5 to 3.5). Moreover, the results of qualitative analysis revealed that the main flaws and inadequacies plaguing governance in the management system of the new city of Golbahar are lack of motivation and sense of belonging to the place in the citizens, non-transparency of the laws and the citizens' mistrust in the authorities.
