The battle can begin now Prime Minister Bill English has announced this year's general election will be held on September 23.
The game changer was most certainly the resignation of John Key as Prime Minister and National will realise they need to work that bit harder for a fourth term now they can't count on his personality for votes.
Mr English would, I am sure, be the first to admit he cannot compete with Mr Key as a people person, so the party's focus looks set to be the stability the National Government has brought to the country since it came to power in 2008.
Mr English said as much as his press conference yesterday to announce the date, when he indicated the economy would be the "central issue".
It was probably a good strategy to put that message out early because he will be wanting to focus attention on the country's sound financial and economic footing. The implication being that he, as Finance Minister, played a big role in that so therefore can be trusted with running the country.
