Police say they are continuing to look for an additional firearm and ammunition they believe may have been held by the man arrested in relation to the shootings on 1 September.
John Tully has been charged with the murder of Work and Income staff members Peggy Noble and Leigh Cleveland, and the attempted murder of colleague Lindy Curtis.
Funerals have been held for Ms Noble and Ms Cleveland.
Police spent last weekend searching a 13km stretch of scrub and bushland along the river near the farm where Mr Tully was arrested, just south of the township.
A spokesperson said the search team, which included specialist firearms dog handlers and dogs from Christchurch and Wellington as well 65 Search and Rescue team members from all over the district, found a black mountain bike with a number of personal items thought to belong to the accused.
