Parties,organizational capacities and external change: New Zealand’s National and Labour parties,candidate selection and the advent of MMP

How and how well do different parties manage similar environmental changes? How do organizations shape parties’ adaptation to change? In 1996 New Zealand replaced its Single Member Plurality (SMP) electoral system with a Mixed Member Proportional (MMP) system. MMP added an overriding proportional tier to national elections and compelled the major incumbent parties, Labour and National, to undertake new tasks: the creation of national lists of candidates and the construction of nationwide campaigns for the ‘party vote’. This paper compares how Labour and National organized candidate selection in response to MMP. It demonstrates how and why Labour possessed organizational capacities to meet these challenges that National lacked before the advent of MMP and for several years after it.
