"The team that have been there since day dot are starting to get pretty tired and need a break and spend time with their families, so it's great we can come down and provide a little bit of relief."
Ms Luckett was in the public information management team - coordinating media releases, managing social media and developing key messages.
Mr Bourton was in the logistics team, coordinating staff and resources at the crisis management hub and supporting relief efforts on the ground.
The duo were deployed for five days but Ms Luckett said it could be extended.
"There's continuing aftershocks and severe weather in the South Island over the next couple of days which may impact the response effort," she said.
Another Bay Civil Defence staffer from the Whakatane office, Megan Edhouse, arrived today to join the effort.
Wellington seemed to be business as usual though the weather was nasty and there were small visible signs of the earthquake, such as construction work to stabilise buildings, Ms Luckett said.
Many agencies were represented in the response effort, from the Ministry of Education to IRD to a raft of scientific advisers.
"It's full on but it's really great."
