From a technical perspective we've got a hammer on the daily chart recently.
narrative wise i think the NZD narrative of the china reopening and the NZD rate advantage has moved over to the EUR so the NZD stronger story seems a little stale now.
correlations suggest higher, GBPNZD and EURNZD and closely correlated and is suggesting GBPNZD higher, rate differentials are higher as well which should help.
