© 2017 The Royal Society of New Zealand. This paper discusses simulated ground motion intensity, and its underlying modelling assumptions, for great earthquakes on the Alpine Fault. The simulations utilise the latest understanding of wave propagation physics, kinematic earthquake rupture descriptions and the three-dimensional nature of the Earth's crust in the South Island of New Zealand. The effect of hypocentre location is explicitly examined, which is found to lead to significant differences in ground motion intensities (quantified in the form of peak ground velocity, PGV) over the northern half and southwest of the South Island. Comparison with previously adopted empirical ground motion models also illustrates that the simulations, which explicitly model rupture directivity and basin-generated surface waves, lead to notably larger PGV amplitudes than the empirical predictions in the northern half of the South Island and Canterbury. The simulations performed in this paper have been adopted, as one possible ground motion prediction, in the ‘Project AF8’ Civil Defence Emergency Management exercise scenario. The similarity of the modelled ground motion features with those observed in recent worldwide earthquakes as well as similar simulations in other regions, and the notably higher simulated amplitudes than those from empirical predictions, may warrant a re-examination of regional impact assessments for major Alpine Fault earthquakes.

For over a decade, an irreplaceable ring laser has been trapped in a cavern 30m below Christchurch port hills. The Carl Zeiss laser was installed in an old World War Two bunker in 1997 until a rockfall after the 2011 Christchurch earthquake sealed the cavern. But now it's been rescued and is fully operational. Professor Jon-Paul Wells is the principal investigator on the ring laser project.

The standard way in which disaster damages are measured involves examining separately the number of fatalities, of injuries, of people otherwise affected, and the financial damage that natural disasters cause. Here, we implement a novel way to aggregate these separate measures of disaster impact and apply it to two recent catastrophic events: the Christchurch (New Zealand) earthquakes and the Greater Bangkok (Thailand) floods of 2011. This new measure, which is similar to the World Health Organization’s calculation of Disability Adjusted Life Years (DALYs) lost from the burden of diseases and injuries, is described in detail in Noy (2014). It allows us to conclude that New Zealand lost 180 thousand lifeyears as a result of the 2011 events, and Thailand lost 2,644 thousand years. In per capita terms, the loss is similar, with both countries losing about 15 days per person due to the 2011 catastrophic events in these two countries. We also compare these events to other potentially similar events.

We examine the role of business interruption insurance in business recovery following the Christchurch earthquake in 2011 in the short- and medium-term. In the short-term analysis, we ask whether insurance increases the likelihood of business survival in the aftermath of a disaster. We find only weak evidence that those firms that had incurred damage, but were covered by business interruption insurance, had higher likelihood of survival post-quake compared with those firms that did not have insurance. This absence of evidence may reflect the high degree of uncertainty in the months following the 2011 earthquake and the multiplicity of severe aftershocks. For the medium-term, our results show a more explicit role for insurance in the aftermath of a disaster. Firms with business interruption insurance have a higher probability of increasing productivity and improved performance following a catastrophe. Furthermore, our results show that those organisations that receive prompt and full payments of their claims have a better recovery, in terms of profitability and a subjective ‘”better off” measure’ than those that had protracted or inadequate claim payments (less than 80% of the claim paid within 2.5 years). Interestingly, the latter group does worse than those organisations that had damage but no insurance coverage. This analysis strongly indicates the importance not only of good insurance coverage, but of an insurance system that also delivers prompt claim payments. As a first paper attempting to empirically identify a causal effect of insurance on business recovery, we also emphasize some caveats to our analysis.

Earthquakes are insured only with public sector involvement in high-income countries where the risk of earthquakes is perceived to be high. The proto-typical examples of this public sector involvement are the public earthquake insurance schemes in California, Japan, and New Zealand (NZ). Each of these insurance programs is structured differently, and the purpose of this paper is to examine these differences using a concrete case-study, the sequence of earthquakes that occurred in the Christchurch, New Zealand, in 2011. This event turned out to have been the most heavily insured earthquake event in history. We examine what would have been the outcome of the earthquakes had the system of insurance in NZ been different. In particular, we focus on the public earthquake insurance programs in California (the California Earthquake Authority - CEA), and in Japan (Japanese Earthquake Reinsurance - JER). Overall, the aggregate cost to the public insurer in NZ was $NZ 11.1 billion in its response to the earthquakes. If a similar-sized disaster event had occurred in Japan and California, homeowners would have received $NZ 2.5 billion and $NZ 1.4 billion from the JER and CEA, respectively. We further describe the spatial and distributive patterns of these different scenarios.

We measure the longer-term effect of a major earthquake on the local economy, using night-time light intensity measured from space, and investigate whether insurance claim payments for damaged residential property affected the local recovery process. We focus on the destructive Christchurch earthquake of 2011 as our case study. In this event more than 95% of residential housing units were covered by insurance, but insurance payments were staggered over 5 years, enabling us to identify their local impact. We find that night-time luminosity can capture the process of recovery and describe the recovery’s determinants. We also find that insurance payments contributed significantly to the process of economic recovery after the earthquake, but delayed payments were less affective and cash settlement of claims were more affective in contributing to local recovery than insurance-managed rebuilding.

We estimate the causal effects of a large unanticipated natural disaster on high schoolers’ university enrolment decisions and subsequent medium-term labour market outcomes. Using national administrative data after a destructive earthquake in New Zealand, we estimate that the disaster raises tertiary education enrolment of recent high school graduates by 6.1 percentage points. The effects are most pronounced for males, students who are academically weak relative to their peers, and students from schools directly damaged by the disaster. As relatively low ability males are overrepresented in sectors of the labour market helped by the earthquake, greater demand for university may stem from permanent changes in deeper behavioural parameters such as risk aversion or time preference, rather than as a coping response to poor economic opportunities.

Early Days Yet, directed by Shirley Horrocks, is a full-length documentary about New Zealand poet Allen Curnow, made in the last months of his life. The poet talks about his life and work, and visits the places of some of his most important poems. It includes interviews with other New Zealand poets about Curnow's significance as an advocate for New Zealand poetry. As Curnow famously mused in front of a moa skeleton displayed in Canterbury Museum: "Not I, some child, born in a marvellous year / Will learn the trick of standing upright here."

This booster's gem was produced by the NFU to mark Canterbury's centennial. The original Canterbury crusaders' dream of a model England colony is shown in settler life re-enactments. The importance of meat and wheat to the region's prosperity is extolled and a progressive narrative — "in one brief century they've turned the wilderness into fertile farms and built their red-roofed homes" — underpins contemporary scenes (cricket, church) and much bucolic (plains, alps) scenery. Trivia: Peter Jackson used an excerpt from the film to open Heavenly Creatures.

This chronicle of the Christchurch Commonwealth Games marked one of the National Film Unit's most ambitious productions. Though a range of events (including famous runs by John Walker and Dick Tayler), are covered, the film often bypasses the pomp and glory approach; daring to talk to the injured and mentioning that most competitors lose. The closing ceremonies of the "friendly games" feature the athletes gathering to — as the official song's chorus put it — "join together". The directing team included Paul Maunder, Sam Pillsbury, and Arthur Everard.

"New Zealand congratulates Peter Snell, one of the fastest men in the world." Middle distance runner Snell sets two world records on the grass track at Lancaster Park, Christchurch, in the 800 yards and half mile. "I was almost horrified at the pace ... I was had it by the time I reached the back straight ... I just went on on the thought of that world record." He reflects on a relaxing trip to Milford Sound, and champion coach Arthur Lydiard is interviewed. Also featured is the 1962 swimming champs at Naenae Olympic Pool under floodlights. Snell died on 12 December 2019.

For her first feature, writer/director Gillian Ashurst (Venus Blue) wanted a “big wide road movie; big skies; big long roads.” Cruising the Canterbury landscapes are small-town dreamers Alice (Heavenly Creature Melanie Lynskey) and Johnny (future Almighty Johnson Dean O’Gorman). The duo’s adventures go awry after encountering a charming American cowboy. Reviews were generally upbeat: there was praise for the talented cast, plus Ashurst’s ability to mix moods and genres. Snakeskin won five awards at the 2001 NZ Film and TV Awards, including Best Film and Cinematography.

This TVNZ doco chronicles New Zealand’s participation in 18 Empire and Commonwealth Games — beginning at Hamilton, Canada in 1930 when a Kiwi team of 18 participated in four sports. A cavalcade of gold medallists (including Yvette Williams, Dick Tayler, Anna Simcic and Neroli Fairhall) recall their glory days at the event which was set up to be “merrier and less stern” than The Olympics. Special emphasis is placed on the three New Zealand-hosted Games: at Auckland in 1950 and 1990, and Christchurch in 1974 (which hastened the local arrival of colour television).

The Ballantynes' Department Store fire in November 1947 claimed 41 lives and left a lasting scar on Christchurch — the city’s biggest single disaster until the 2011 earthquake. The events of that spring day are explored in this short film which intersperses archive footage with a fictional account of workers and customers in the tailoring department as the dramas of everyday life are suddenly overwhelmed. It was directed by Aileen O’Sullivan, shot by Alun Bollinger and made with the NZ Drama School graduating class of 2002 (with music by Gareth Farr).

Gerard Smyth's acclaimed documentary about the Christchurch earthquakes is the story of people coping — for better or worse — with the huge physical and emotional toll that the quakes, and continuing aftershocks, inflicted on them, their homes and their city. It began as a home movie while the devastation of September was surveyed (with thanks given that no-one had been killed); but, as shooting of the recovery continued, the February quake compounded the destruction and claimed 182 lives (including their researcher and 16 colleagues at CTV).

Chimney Book takes rubble from the Christchurch earthquake, and turns it into the building blocks of a film exploring life in the quake zone. Christchurch musician Blair Parkes took bricks from his chimney — destroyed in the 22 February 2011 aftershocks — painted a letter or symbol on each, then scanned them into his computer. Sound and word form the spine of the result, which is part diary, part experimental film. Parkes explores his experiences of living in Christchurch since the quake through words like 'dust', 'memory', 'place', and a question: 'is it over?'

This promotional travelogue, made for the Christchurch City Council, shows off the city and its environs. Filmed at a time when New Zealand’s post-war economy was booming as it continued its role as a farmyard for the “Old Country”, it depicts Christchurch as a prosperous city, confident in its green and pleasant self-image as a “better Britain” (as James Belich coined NZ’s relationship to England), and architecturally dominated by its cathedrals, churches and schools. Many of these buildings were severely damaged or destroyed in the earthquakes of 2010 and 2011.

TVNZ's long running religious and choral music programme visits Christchurch's Anglican cathedral. Before its devastation by earthquakes, it was the centre of the city and one of the most celebrated of its great Gothic buildings. It could also claim to be "the most visited, the most accessible and best known church in New Zealand". Host Graeme Thomson explores the cathedral, its chapels and bell tower and outlines its history. He interviews Dean John Bluck and introduces hymns and songs of praise sung by the cathedral's choir and an ecumenical congregation.

In this episode of the influential New Zealand architecture series, dapper tour guide David Mitchell looks at the 'Christchurch Style'. He begins with the humble baches on Taylor's Mistake's cliffs, before focusing on the Euro-influenced brutalism of Miles Warren and the "flamboyant" practice of Peter Beaven (earthquake victims SBS House, and Lyttelton Tunnel's "fifth ship" are featured); and the cottage's modern descendent: Don Donnithorne's post-war home. Warren intriguingly compares his process designing Christchurch Town Hall with Jørn Utzon's Sydney Opera House.
