CauseA succession of low pressure systems moved out to the east, dragging in blustery southeasteries and driving a succession of wet patches into Marlborough and beyond. On the 24th, a deepening low that had developed in the western Tasman Sea was close enough to bring stormy weather to New Zealand. On the 25th, the low remained slow moving over the North Island, while a stationary front combined with a moist east to south-east flow to bring rain to North Canterbury and Marlborough. On the 27th, the low moved slowly to the east of the North Island, bringing heavy rain to the Wellington region until the 28th.

CauseA succession of low pressure systems moved out to the east, dragging in blustery southeasteries and driving a succession of wet patches into Marlborough and beyond. On the 24th, a deepening low that had developed in the western Tasman Sea was close enough to bring stormy weather to New Zealand. On the 25th, the low remained slow moving over the North Island, while a stationary front combined with a moist east to south-east flow to bring rain to North Canterbury and Marlborough. On the 27th, the low moved slowly to the east of the North Island, bringing heavy rain to the Wellington region until the 28th.

Affected LifelineThe Clevedon-Kawakawa Road - the main road into Kawakawa Bay - was closed on the 24th as a big slip on Turei Hill moved further. The slip had come down at the beginning of the month and partially blocked the road and another 500 cubic metres of earth came down on to the road at the weekend after heavy rain. The slip moved about another 45 mm over 12 hours on the 29th. 1,500 local people were forced to use a longer alternative route, travelling an extra 100km, or catch a free ferry to Pine Harbour, adding at least an hour to their journey to Auckland. The road was reopened to a single lane on the 26th September, with traffic lights to control the flow of vehicles.

EvacueesSix properties at Kawakawa Bay were deemed unsafe due to the risk of another landslip happening at any time. Owners of the property at the top of the slip voluntarily evacuated on the 24th. On the 29th, residents of five properties at the bottom of the slip were asked to evacuate by Manukau City Council. On the 3rd October, residents of the five houses below the slip were allowed to return to their homes.

ImpactStudents who normally went to school in Clevedon used a room at Orere School and were taught by their usual teacher.

ImpactBusinesses in the Kawakawa and Clevedon areas lost work due to loss of through traffic.
