I'm sure it was Winston Peters (NZFirst Party), who got to be the "kingmaker". He got to choose either National Party or Labour Party to form a government. Winston Peters is a Freemason. I saw him do this freemason sign with his hand half under his jacket at belly hight while thanking the electoral college.
They should rename NZFirst to NZLast party as Winston Peters seems to be a total 180degrees turncoat.
