Opposition parties fear a new department to control the rebuilding of Christchurch will be Wellington-centric and not allow the community to have its fair say in decisions. The Labour Party's spokesperson on the Canterbury Earthquake Recovery, Clayton Cosgrove, spoke to our political editor Brent Edwards.

It's been revealed that not a single one of New Zealand's 315 police buildings constructed before 2011 have had a full earthquake safety check. Canterbury's district health buildings and a central Wellington cinema are among other major structures needing checks. Phil Pennington joins us with the details.

The cartoon depicts the Minister of Earthquakes Gerry Brownlee, with a portaloo in place of a head. He holds in his hand a document which reads 'Govt appointed quake panel (Shipley etc) paid twice normal fees: $1000 - 1400 daily'. A voice from inside the toilet says 'It's because they're high calibre people!' Context: Earthquake Recovery Minister Gerry Brownlee lobbied his colleagues to pay a Government-appointed panel more than twice the recommended rate because he claimed they would not do it for less - even though he never asked them. On Mr Brownlee's advice, the Cabinet more than doubled the pay rates for the panel from the recommended fees, which was a daily rate of $360 to $655 for the panel chairman and $270 to $415 for panel members. The Cabinet increased this to $1400 a day for the chairman and $1000 a day for the other members. (NZ Herald, 9 August 2011) Quantity: 1 digital cartoon(s).

This study investigates the uncertainty of simulated earthquake ground motions for smallmagnitude events (Mw 3.5 – 5) in Canterbury, New Zealand. 148 events were simulated with specified uncertainties in: event magnitude, hypocentre location, focal mechanism, high frequency rupture velocity, Brune stress parameter, the site 30-m time-averaged shear wave velocity (Vs30), anelastic attenuation (Q) and high frequency path duration. In order to capture these uncertainties, 25 realisations for each event were generated using the Graves and Pitarka (2015) hybrid broadband simulation approach. Monte-Carlo realisations were drawn from distributions for each uncertainty, to generate a suite of simulation realisations for each event and site. The fit of the multiple simulation realisations to observations were assessed using linear mixed effects regression to generate the systematic source, path and site effects components across all ground motion intensity measure residuals. Findings show that additional uncertainties are required in each of the three source, path, and site components, however the level of output uncertainty is promising considering the input uncertainties included.

Shows Minister for Christchurch Earthquake Recovery Gerry Brownlee as Pontius Pilate washing his hands of the rental crisis in Christchurch. In the background is Jesus burdened with the cross and representing the 'rental crisis'. Context: The rental housing situation in Christchurch is at crisis point and is causing huge stress for people unable to find suitable accommodation. Earthquake Recovery Minister Gerry Brownlee said last month that the rental housing crisis was best left to the market, but Gatonyi said his stance was "totally flawed".

Following a major earthquake event, essential public amenities such as medical facilities and transport networks need to remain functional - not only to fulfil their ongoing role in serving the community but also to cope with the added and immediate demand of a population affected by a natural disaster. Furthermore, the economic implications of wide spread damage to housing and commercial facilities should not be discounted. A shift in design approach is required that is consistent with current trends towards performance based building design. The present aim is to achieve seismic energy dissipation during the earthquake event, without the aftermath of damage to structural elements, whilst maintaining design economies. Structures permitted to rock on their foundations and provide recoverable rotations at the beam-column interfaces offer significant advantages over those using conventional ductile detailing. A jointed construction philosophy can be applied whereby structural elements are connected with unbonded prestressing tendons. Supplemental damping is provided by replaceable flexural steel components designed to deform inelastically. For this research a multi-storey test building of one quarter scale has been constructed and tested on an earthquake simulator at the University of Canterbury. A computer model has been developed and a set ofpreliminary design procedures proposed.

This paper presents an overview of the soil profile characteristics at strong motion station (SMS) locations in the Christchurch Central Business District (CBD) based on recently completed geotechnical site investigations. Given the variability of Christchurch soils, detailed investigations were needed in close vicinity to each SMS. In this regard, CPT, SPT and borehole data, and shear wave velocity (Vs) profiles from surface wave dispersion data in close vicinity to the SMSs have been used to develop detailed representative soil profiles at each site and to determine site classes according to the New Zealand standard NZS1170.5. A disparity between the NZS1170.5 site classes based on Vs and SPT N60 investigation techniques is highlighted, and additional studies are needed to harmonize site classification based on these techniques. The short period mode of vibration of soft deposits above gravels, which are found throughout Christchurch, are compared to the long period mode of vibration of the entire soil profile to bedrock. These two distinct modes of vibration require further investigation to determine their impact on the site response. According to current American and European approaches to seismic site classification, all SMSs were classified as problematic soil sites due to the presence of liquefiable strata, soils which are not directly accounted for by the NZS1170.5 approach.

Text above the image reads 'Time capsule discovered under founder's statue-' The statue of John Robert Godley, the founder of Christchurch, has toppled and a time capsule has been uncovered in the rubble by three rescue workers. One of them reads the document he has pulled out of the capsule and it says 'Personally I favoured Akaroa...' Context - the Christchurch earthquake of 22 February 2011 after which 2 time capsules were found under the John Robert Godfrey statue - they have been sent to Museum experts to open. Akaroa was largely unaffected by the earthquake. A Nelson newspaper 'The Colonist' in an article published in 1918 about the time capsule in Christchurch said, "This statute of John Robert Godley executed by Thomas Woolner was erected in the west side of the Cathedral Square by the Provincial Government of Canterbury, and unveiled by the late Sir Charles Christopher Bowen on August 6 1867, it was moved to this site in March 1918."

Text top left reads 'Downsizemic activity' and a seismic graph zigzags wildly but gradually tails off into the words 'Interest rates' which take a serious downwards trend. Context - The Christchurch earthquakes of 4 September 2010 and 22 February 2011 which have had an impact on an already stagnating economy. The Reserve Bank has made a relatively large 50-point cut in its benchmark interest rate, the Official Cash Rate (from 3% to 2.5 per cent). Critics say that inflation is already running unacceptably high and there is a threat of much higher inflation in a year or two when the rebuilding of Christchurch begins to put pressure on limited resources. The Reserve Bank acknowledged these factors, but it has chosen instead to focus on the immediate impact of the earthquake on the economy and particularly on all-important business and consumer sentiment.

The level of destruction from the 2011 Christchurch earthquakes led to changes in the New Zealand seismic building code. The destruction showed that the NZ building codes did not fully performed to expectation and needed Improvement to ensure that impact of future earthquakes would be minimised. The building codes have been amended to improve buildings resilience to earthquake and other related extreme loading conditions. Rebuilding Christchurch with the new modifications in the seismic building code comes with its own unique challenges to the entire system. This project investigates the impact of rebuilding Christchurch with the new seismic Building codes in terms of how the new changes affected the building industry and the management of construction.
