North Island

Multi HazardMulti Hazard at North Island
Comments:

CauseThe low pressure area which on the 18th affected the general Dominion weather moved from the area of Campbell Island to the east of New Zealand on the 19th, but another depression developed on the afternoon of the 19th between the Chatham Islands and the South Island.

CauseThe steady rain and a strong northerly wind in Auckland on the night of the 20th were the result of a cold front which moved across the Dominion. It was associated with another of the series of low pressure areas which have moved across the Tasman in the past week and which was affecting the weather throughout New Zealand on the 20th. The centre of the depression was to the south-west of the South Island.

Physical CharacteristicAt midnight on the 20th the barometer reading in Auckland was 29.12 in (986 hPa). Pressure at the centre of the depression was 28.64 in (970 hPa).

DurationThe weather event lasted from the 18th to the 21st of June.

ImpactA strong westerly wind coinciding with exceptionally high tides caused some flooding along the foreshore at Onehunga on the 21st and 22nd. It was estimated that the tide reached its highest level for over 15 years.

ImpactCars passing over Mangere Bridge on the afternoon of the 21st were drenched with spray as waves broke with violence over the causeway and at one stage the lower portion of the bridge was awash. Roads along the foreshore of the low lying area of the Mangere and Onehunga waterfronts were littered with seaweed and flotsam left by the receding tide waters.

Affected LifelineThe sea broke over the end of the Onehunga Wharf and washed the roads leading to the wharf.

Peak Water LevelAlthough official measurements were not taken, it was estimated that the tide on the morning of the 22nd at Onehunga had a range of nearly 20 feet (6.1 m), which was the highest for over 15 years.

ImpactFarms were flooded and a house was completely surrounded by the water which was over three feet (0.91 m) deep and flowing through the house.

ImpactAn exceptionally high tide, driven by a strong north westerlywind, combined with flood waters in the Piako River to flood hundreds of acres in the Kopuarahi district on the night of the 20th. The water had not receded by the 23rd.

ImpactThe main Thames-Auckland road was covered with water to a depth of about a foot (0.3 m), and 150 acres of land flooded, when tide and storm waters, backed by wind, broke through a gap in the stopbank at Waitakaruru. Traffic was held up for a period while the inundation was at its worst.

ImpactA garage was entered by water and the floor was covered to a depth of two feet (0.61 m), and a dwelling at the back was also entered.

Stock DamageFour pigs were lost.

ImpactThe water came up between the two bridges, and flooded almost the whole of the area between the school and the main bridge.

ImpactThe township was flooded, although no water entered any dwellings. The water reached to within five inches (13 cm) of the floor level of a store.

CommentThe flood was the worst that Waitakaruru had experienced for 10 years.

ImpactThe Waitakaruru township had more than two feet (0.61 m) of water over the main road on the night of the 20th and the flood spread from the township to the canal near the dairy factory. Flood waters did not reach high enough to enter shops but outhouses were badly flooded.

ImpactThe flood overtopped the bank of the Karita canal between Waitakaruru and Miranda spreading into the surrounding country. It was the first high tide to top the stopbanks since they were constructed 15 years ago. The flood also topped the stopbank in various places between Waitakaruru and the Karita canal.

ImpactBreaching sand dunes on the Waitara foreshore on the night of the 18th, raging seas swept on to batter two cottages situated about 50 feet above the normal high water mark. The cottages were situated in a depression behind sand dunes about 220 yards west of the mouth of the Waitara River.

EvacueesThe occupants were forced to evacuate the cottages, removing their furniture and belongings before the invading waters reached their height.

Property DamageWhipped into fury by a strong westerly gale, waves scoured the sand dunes and occasional waves broke over the top of the sand hills. The waves battered the cottages with sufficient force to break windows and do structural damage.

ImpactDrift wood and sand were piles around the cottages on the 19th to a depth of four feet (1.22 m).

Peak Water LevelPassing the cottage the waves dashed through a pine plantation and swamped Centenial Avenue on the lake side of the beach reserve. Water swirled around the foundations of the Waitara Swimming and Life-Saving Clubs new clubhouse, about 45 feet (13.7 m) above normal high water, and the surf tipped over a concrete pillbox.

ImpactBreaching a boulder wall in three places and sweeping the breastwork away at a number of other points, heavy seas broke on to the railway yards at New Plymouth on the 21st.

Peak Water LevelThe highest tide for many years was recorded in Wellington on the 19th. At high tide, at 4.36 p.m., a height of 5 ft 11 in (1.80 m) was marked at the office of the Wellington Harbour Board. The normal spring tide would have been about 4 ft 6 in (1.37 m). It was the highest tide in the memory of old Harbour Board officials.

DamageWater seeped into the basements of many buildings on the waterfront and it is expected that some damage was done to the goods stored.

ImpactThe basement of the General Post Office was badly flooded.

Affected LifelineBlown by a westerly wind, waves were breaking over the Hutt-Eastbourne road at high tide. In Lowry Bay, York Bay, Maheno Bay and Day's Bay the waves were breaking right across the road, leaving quantities of driftwood and flotsam.

ImpactThe height of the tide was most apparent in the lower parts of the Hutt River. Areas never before seen under water by most of the inhabitants were well covered.

Comment"When the barometric pressure is low at the new moon high tides are often caused", said a Harbour Board official, "This is the only reason I can give for this abnormally high tide".

ImpactBreaching sand dunes on the Waitara foreshore on the night of the 18th, raging seas swept on to batter two cottages situated about 50 feet above the normal high water mark. The cottages were situated in a depression behind sand dunes about 220 yards west of the mouth of the Waitara River.

EvacueesThe occupants were forced to evacuate the cottages, removing their furniture and belongings before the invading waters reached their height.

Property DamageWhipped into fury by a strong westerly gale, waves scoured the sand dunes and occasional waves broke over the top of the sand hills. The waves battered the cottages with sufficient force to break windows and do structural damage.

ImpactDrift wood and sand were piles around the cottages on the 19th to a depth of four feet (1.22 m).

Peak Water LevelPassing the cottage the waves dashed through a pine plantation and swamped Centenial Avenue on the lake side of the beach reserve. Water swirled around the foundations of the Waitara Swimming and Life-Saving Clubs new clubhouse, about 45 feet (13.7 m) above normal high water, and the surf tipped over a concrete pillbox.

ImpactBreaching a boulder wall in three places and sweeping the breastwork away at a number of other points, heavy seas broke on to the railway yards at New Plymouth on the 21st.

Peak Water LevelThe highest tide for many years was recorded in Wellington on the 19th. At high tide, at 4.36 p.m., a height of 5 ft 11 in (1.80 m) was marked at the office of the Wellington Harbour Board. The normal spring tide would have been about 4 ft 6 in (1.37 m). It was the highest tide in the memory of old Harbour Board officials.

DamageWater seeped into the basements of many buildings on the waterfront and it is expected that some damage was done to the goods stored.

ImpactThe basement of the General Post Office was badly flooded.

Affected LifelineBlown by a westerly wind, waves were breaking over the Hutt-Eastbourne road at high tide. In Lowry Bay, York Bay, Maheno Bay and Day's Bay the waves were breaking right across the road, leaving quantities of driftwood and flotsam.

ImpactThe height of the tide was most apparent in the lower parts of the Hutt River. Areas never before seen under water by most of the inhabitants were well covered.

Comment"When the barometric pressure is low at the new moon high tides are often caused", said a Harbour Board official, "This is the only reason I can give for this abnormally high tide".
