How many 1:100 year events have you had in the last five years? 

Our budgets are having to repair the ravages of climate change with numerous assets suddenly under capacity as well.  Our “best for asset” renewal approach is not affordable.  We can repair three culverts for a 1:50 year event but the community still suffers flooding in a two-year event in five other locations. 

We can fully repair three slip sites but the road is still closed in four other places.  We can’t restore access with the same level of service.  Time for “best for portfolio” thinking!  Portfolio thinking stretches our limited budget increasing the quantity of asset improvements. 

Through innovative approaches to risk, criticality and programming, clients can achieve meaningful rangatiratanga (leadership) and kaitiakitanga (stewardship).  This portfolio thinking delivers improved outcomes for our communities and optimises the resilience of the whole asset portfolio.
