1. A moving picture coding apparatus for coding a current block, the moving picture coding apparatus comprising:
a processor; and
a non-transitory memory,
wherein the processor performs, using the non-transitory memory, processes including:
deriving a first candidate from a first motion vector that has been used to code a first block;
determining whether a total number of one or more candidates including the first candidate is less than a maximum candidate number;
deriving a second candidate having a second motion vector after deriving the first candidate when the total number of the one or more candidates including the first candidate is less than the maximum candidate number, the second motion vector including a zero vector;
selecting a candidate from a plurality of candidates, the plurality of candidates including the first candidate and the second candidate; and
coding the current block using the selected candidate.
