"Parliamentary Friendship" groups are groups of congresspeople/members of parliament who voluntarily organise themselves to promote parliamentary relations between their own Parliament and another country's (or even a region's group of countries') parliament(s), and, in a broader scope, to foster the bilateral relations between said countries.Parliamentary friendship groups play an important role in New Zealand’s engagement in inter-parliamentary relations, with group members often called upon to participate and host meetings for visiting delegations from the other part, as well as often being invited by the other country's parliament to visit it.
