Media: Freedom of the press is guaranteed in Article 18 of the Constitution of the United Republic of Tanzania of 1977, Chapter 2. Print and electronic media are active, but their impact is limited largely to the urban areas. According to Reporters Without Borders, there is genuine freedom of press in Tanzania and its media sector is large and mostly acts responsibly. One exception is Zanzibar where the semi-autonomous government often attacks the independent press, accusing it of being a 'threat to national unity' at the first sign of criticism. According to other sources, self-censorship is reported to be widely practised, and some instances of harassment towards journalists investigating sensitive subjects like corruption and power abuse have been reported as well. Furthermore, it has been revealed that some journalists accept bribes in order to either publish or ignore certain information. Members of Parliament (MPs) reportedly offer bribes to reporters so that they can publish good stories about the MPs' activities (also known as 'check book' or 'envelope journalism'). President Kikwete has encouraged the media to report on corruption and abuse of power, and there are reports on improved independent and balanced media coverage. The government exerts influence via state newspapers, radio and television stations. The legislative framework still contains acts that have been used to curb media freedom by invoking 'national security concerns'. According to Freedom House 2010, the media report widely on corruption and play an important role in the fight against corruption. During the Central Bank and public procurement scandals, which led to the firing of the Central Bank's governor and resignation of the Prime Minister, the media have been accredited for their persistent coverage of the stories, which is said to have pressured the government to establish the parliamentary committee that is investigating the scandals. According to Afrobarometer 2008, 79% of the surveyed households agree with the statement that the media should constantly investigate and report on corruption and government mistakes. This indicates a genuine public trust in journalists. In 2008, 5 local journalists were awarded by the Media Institute of Southern Africa on corruption and good governance. Reporters Without Borders 2010 ranks Tanzania 41st out of 178 countries, while Freedom House 2010 ranks Tanzania 105th out of 196 countries and describes its press environment as 'partly free'.

Civil Society: Opposition voices in the party system and civil society have traditionally been very weak in Tanzania. All basic civil liberties, such as freedom of speech, association and religion, are guaranteed in the constitution, but there are frequent reports on violations of these civil rights by state authorities. Civil society has gradually consolidated itself since the democratisation process which started in the early 1990s. However, civil society organisations are still politically weak, fragmented and often ignored by political leaders. According to Global Integrity 2010, it is not uncommon for the Tanzanian government to make attempts to restrict media coverage of corruption-related issues through unofficial means, such as restricting access by disfavoured media outlets. In addition, according to the report, the government may occasionally censor material prior to its publication, especially politically sensitive or damaging corruption-related material. Nevertheless, the report assesses that, overall, it is safe for journalists in Tanzania to report on corruption.

Research on Poverty Alleviation (REPOA): REPOA is a non-profit NGO that conducts research, coordinates training and promotes dialogue on poverty reduction and governance issues, including corruption. The organisation also conducts workshops and training seminars. REPOA is also publishing research studies and articles on good governance and corruption. The most notable publications are an April 2008 study on regional perceptions on corruption in Tanzania, a July 2008 study on corruption in local taxation systems and a September 2009 study on citizens' changing views on taxation systems.

African Parliamentarians Network Against Corruption (APNAC): APNAC is a leading all-party parliamentary anti-corruption network in Africa. Its main work is to promote good governance and to strengthen parliamentary capacity to fight corruption. It has a local chapter in Tanzania, where TI-Tanzania is the official Secretariat of APNAC-TZ. APNAC-TZ has carried out various activities in Tanzania, including investigation of corruption scandals in different government parastatals, and reported the findings to the Parliament, as well as given recommendations on amendments of Parliament's Standing Orders. The national chapter has also helped to get Tanzania to ratify the African Union Convention on Preventing and Combating Corruption.

Policy Forum: Policy Forum is a network of NGO's working to increase civil society's influence on policy making, focusing on three main areas: Local Governance, Public Money and Active Citizen's Voice. Policy Forum organises workshops, give comments on proposed legislation and has issued a number of reports on subjects such as transparency in local governance, oversight of revenues from extractive industries and budget analysis.

Legal and Human Rights Centre (LHRC): LHRC is an NGO that promotes human rights, conducts awareness-raising and provides legal assistance through a number of legal aid clinics. LHRC has set up watch panels monitoring the performance and accountability of the government, the parliament and the judiciary and the centre issues reports based on the panel's findings as well as annual human rights reports.
