With the reduction in size of New Zealand's 10-, 20-, and 50-cent coins in 2006, older cent coins began to be phased out in both countries. However, $1, $2, and $5 pieces remained in use. Although a 2010 commemorative Cook Islands coin set in denominations 1-, 2-, 5-, 10-, 20-, and 50-cents and a bimetallic $1 have been minted with a similar size to some of the newer New Zealand ones, these coins are for collectors and intended to raise money for the Cook Islands government, rather than for release into circulation.
