Free trade policy has not been as popular with the general public. Key issues include unfair competition from countries where lower labour costs are reducing prices and the loss of well-paying jobs for producers abroad. As soon as the agreements go beyond the regional level, they need help. The World Trade Organization intervenes at this stage. This international body contributes to the negotiation and implementation of global trade agreements. In the modern world, free trade policy is often implemented by a formal and reciprocal agreement between the nations concerned. However, a free trade policy may simply be the absence of trade restrictions. Once negotiated, multilateral agreements are very powerful. They cover a wider geographic area, giving signatories a greater competitive advantage. All countries also give themselves the status of the most favoured nation – and grant the best conditions of mutual trade and the lowest tariffs.
Economists have tried to assess the extent to which free trade agreements can be considered public goods. First, they deal with a key element of free trade agreements, the system of on-board tribunals, which act as arbiters in international trade disputes. These serve as a clarification of existing statutes and international economic policies, as confirmed by trade agreements.  A free trade agreement is a pact between two or more nations to reduce barriers to trade between imports and exports. Under a free trade policy, goods and services can be bought and sold across international borders without government tariffs, quotas, subsidies or bans. First, the parties that signed a free trade area applicable to trade with non-parties to that free trade area at the time of the creation of that free trade area must not be higher or more restrictive than tariffs and other rules applicable in the same signatory countries prior to the creation of the free trade area. In other words, the creation of a free trade area to give preferential treatment to their members is legitimate under WTO law, but parties to a free trade area are not allowed to treat non-parties less favourably than before the creation of the territory. A second requirement under Article XXIV is that tariffs and other trade barriers must be eliminated primarily for all trade within the free trade area.  Or there are guidelines that exempt certain products from duty-free status in order to protect domestic producers from foreign competition in their industries. Under a free trade agreement, countries may agree not to discriminate against service providers or investors in other countries and not to create certain barriers that limit trade and investment.
This will allow New Zealand exporters to open up new opportunities in areas such as private education, ict services, professional services and transportation services, and will provide more security and transparency for New Zealand suppliers and investors. A free trade agreement between two countries or a group of countries can be used to define the rules on how countries deal with each other when it comes to doing business together.
