Among other features of the agreement, Okuk argued for a larger Papua New Guinea stake in the project (closer to 51%), so that all the profit did not go directly into the hands of foreign capitalists, and Papua New Guinea could receive some benefit. The total flow of capital out of the country from the Bougainville project is staggering, given the overall size of the Papua New Guinea economy. In the 1973-75 period, for example, it is estimated that capital outflow, including repatriation of profits and loan repayments, will be more than $100 million annually. Even after the bulk of loans has been paid off, by 1981-82, capital outflow will continue at an estimated rate of $30 million annually. Although no accurate estimates exist concerning the proportion of expatriates' salaries that will ultimately leave the country, one would be safe in saying that a good proportion of expatriates' high wages will ultimately leave Papua New Guinea. Okuk supported another National Party member, John Kaupa, both in the debate over expatriate management of the Chimbu Coffee Cooperative and speaking out against the degradation of Highlanders in the Highlands Labour Scheme. He presented the many abuses he had observed while associated with the cooperative and argued that, "Many co-operatives in Papua New Guinea are just window-dressing for white capitalists. As far as our society is concerned, you can name any white businessman in the Highlands. They run the society. Only the name represents the Chimbu people. Who benefits from the societies—the white men. Land reform was taken up by the Parliamentary Leader of National Party, Thomas Kavali, who was Minister for Lands in 1974 when four land reform bills were passed, and Okuk spoke in support of subsidized loans for citizens to buy back plantations from foreign interests prior to the introduction of this legislation. As Minister for Agriculture, he sponsored numerous bills directed at localization of the coffee industry. The Coffee Marketing Board, although established by the administrator in 1964, had not developed along the same lines as the Copra Marketing Board; it was dominated by expatriates and responded to the needs of plantation owners and processors rather than the small indigenous growers. His initial legislation addressed the functioning of the Coffee Marketing Board. First was the Coffee Marketing Board Stabilization Fund, which he brought as a bill on 16 June 1972. Immediately afterwards, he introduced a bill to increase the size of the Coffee Marketing Board to include more growers. In the course of 1973, he repeatedly addressed the problems plaguing the coffee industry, including abuses in buying coffee from the indigenous small growers, as well as the management of coffee cooperatives.
