It looks like your domain ride24.co.nz is still not pointing to WordPress.com name servers: http://whois.domaintools.com/ride24.co.nz
For the domain mapping to work, the nameservers need to be set to the following values:
ns1.wordpress.com
ns2.wordpress.com
ns3.wordpress.com
Please contact your registrar for assistance in updating the name servers. You can find additional support documentation here: https://en.support.wordpress.com/domains/change-name-servers/
