反向Pn速度已被确定为新西兰北岛东南部Wairarapa地区的区域震源。该区域最东部的数值为8.64（±0.13）km/s，Wairarapa中部为8.90（±0.13）km/s，这与该区域下方深度较浅的俯冲太平洋板块相一致。惠灵顿和Wairarapa地区之间的8.22公里/秒的值被解释为两个地方之间的折射率以上的速度结构的可能差异。
Reversed Pn velocities have been determined from regional earthquake sources for the Wairarapa region in the southeast North Island, New Zealand. Values were 8.64 (±0.13) km/s in the easternmost part of the region and 8.90 (±0.13) km/s in the central Wairarapa, which are consistent with subducted Pacific plate lying at shallow depth under the region. A value of 8.22 km/s between Wellington and the Wairarapa region is interpreted as a possible difference in the velocity structure above the refractor between the two localities.
