The frenetic activity is all about National and Labour grappling with one another for the early election-year political initiative and - hopefully - retaining it. Or at least preventing the other party from doing so.
Setting the agenda and forcing Labour to talk about what National wants to talk about is one of the primary tasks of the Prime Minister's address today - just as Cunliffe will seek to do likewise on Monday ahead of next week's first sitting of Parliament in 2014.
Key has chosen education as the main focus of his speech because he believes elections are won and lost on how governments handle matters fundamental to people's daily lives, such as law and order and economic management.
Last year's disappointing PISA results showing that New Zealand school students' performance in reading, maths and science had slipped against some countries has left National vulnerable in a portfolio area where it had previously felt it held the advantage over Labour in terms of putting forward policies that parents wanted to see implemented but which did not square with Labour ideology.
National also needs to show it is just as fresh policy-wise as it was when it took office five years ago. Key's speech must counter Cunliffe's repeated refrain that the governing party has run out of ideas to lift living standards.
That is doubly important given mortgage-holders - a crucial voting bloc - are likely to be hit by Reserve Bank-driven hikes in interest rates this year.
Lastly, Key's speech needs to mount a convincing argument as to why a Labour-Greens coalition government would be unworkable. He needs to go beyond mere rhetoric and cite concrete examples of where the positions of the two supposed Opposition allies are irreconcilable.
Key yesterday seized on exploratory deep sea oil drilling as one such example. That issue has been ripe for National's picking for months.
The challenge for the Labour and Greens leaderships is to display much more sophisticated political management of the issues that divide the two parties, rather than scoring points off one another which is only to National's overall advantage.
