BST to NZST Time Converter
About this conversion
NZST is New Zealand Standard Time (UTC+12), the winter time in New Zealand. Compared with BST (UTC+1), it is 11 hours ahead.
NZST applies from early April to late September, so the gap of 11 hours holds for most of the UK summer. In the UK winter New Zealand is on NZDT and the gap grows to 13 hours.
When the time difference changes
Both sides keep a fixed offset, so the gap does not change in the next two years.
