New Zealand time to end DST

Hi Small anomaly for New Zealand timezone DST stop time, the Time Act 1974 states (2) Any period prescribed in any Order in Council made under subsection (1) of this section shall commence at 2 a.m. New Zealand standard time on the day, being a Sunday, specified in the Order in Council, and shall cease at 2 a.m. New Zealand standard time on the day, being a Sunday, specified in the Order in Council or in any subsequent Order in Council. In NZ we are told accordingly to put clocks forward at 2 (to 3) and back at 3 (to 2). In my interpretation of this the zoneinfo is incorrect for NZ and should be stopping at 3am (since 1974) Regards Chris
