The same people will be doing the same job but you expect a different result. How?
Twyford is responsible for Economic development, not Robertson. Robertson isn't sitting around looking for things to do. He is busy enough with finance.
Governments rely on big teams, the jobs are too big for one person to run a government alone.
How? Has the Govt been stellar? No. So will they be short sighted enough to rely on the PM and all will be good? No. If they are smart they will recognise their in experience showed. They would want to remedy that, assuming that they have learned. They pulled Twyford off Kiwibuild. If they are smart they will learn from past mistakes, that my basis
Robertson is busy with Finance. yes, Im sure he is. That doesn't mean for 60 hours a week he is adjusting Finance. Finance gets allocated. He and the PM will want to be sure their direction is being advanced. Both for the obvious reason that they want delivery, but also that they are well aware the public is watching. You can forgive a brand new team, inexperienced, but not forever. Everyone is well aware of that.
Big teams yes. The PM is like a good CEO. They do nothing, they just make sure the team down and the team down below that are performing.
Your post seems to indicate that what happened from day one in this Govt will be repeated, that's fine. I put forward that they have learnt, and that any MPs that have not done well will be less involved, and that the PM and the Finance Minister are well aware of that.
Thats my take, we can see how it pans out.
