The National Rifle Association of New Zealand is the national body for fullbore target shooting, based at the Trentham Rifle Ranges on Messines Avenue, Trentham, in Upper Hutt. Its history at Trentham goes back to 1892, when Lieutenant Colonel Joseph Sommerville laid out the Sommerville Range on a farm there, and the national championships were held at Trentham again in 1895. The association's own history traces its national championships back to 1861.
The association's website gives shooters the organisation's constitution, shooting rules, links to member clubs, upcoming events, news and results. It is aimed at new shooters who want to try target rifle shooting, existing members who need up-to-date information, and the media and others interested in its position on fullbore target shooting. Members can list items for sale on the site, and those listings run for up to two months. The website says the association hopes new members will be attracted through its clubs and associations.
