However, this could be weakened through Prime Minister John Key's eagerness to sign the "all or nothing" agreement, with extended patents and provisions which would allow Big Pharma to challenge Pharmac's decision making process.
This would result in increased costs for essential medicines. As Pharmac has a limited budget, the brunt of these costs would be borne by patients filling their prescriptions.
People most likely to have chronic diseases are in lower socioeconomic groups, so the people who need medicines the most are those least able to afford them.
New Zealand's anti-tobacco legislation will also be threatened. If provisions on investor-state dispute settlements are included, companies such as Philip Morris or British American Tobacco could sue the New Zealand Government in overseas courts if laws are seen to damage their investments.
The TPPA would become a weapon similar to the trade agreement Australia had with Hong Kong which allowed the Australian Government to be sued over plain packaging of cigarettes, except the TPPA would be much stronger.
As the negotiations are held in secret, knowledge of the agreement must come from leaked texts, published on websites such as the Citizens Trade Campaign.
It has long been recognised that prevention (in this case, of chronic diseases) is the best cure. It's cheaper, more effective and supports basic human rights.
However, many provisions in the TPPA threaten New Zealand's ability to legislate for our best interests.
Instead, our patent and public health laws (among others) are to be decided in Washington.
Here's hoping our leaders value the health of New Zealand's citizens over the rights of multinational corporations.
