Harawira becomes leader of the new joint "Internet Mana" party; Mana and the Internet Party will pool resources and run on a joint ticket for the party vote.
No prizes for guessing who will be paying the bills.
Harawira's real coup is to secure for Mana three of the first four places on the new party's list. But it is conceivable that a rejuvenated Mana might win two or three more of the Maori electorates with Harawira's Te Tai Tokerau.
That would block the Internet Party from getting an MP off the list unless the party vote for the joint party were to top 2 to 3 per cent.
Harawira, wisely, has also secured an escape route which would allow Mana to exit from the arrangement at short notice.
Furthermore, the whole agreement lapses six weeks after the election unless efforts are made to renew it. That suggests both parties do not see yesterday's deal as a long-term arrangement.
It is before the election that matters most, however. The new party could yet be the surprise package of the coming election - especially if the other centre-left parties continue to flounder.
At a minimum, the novelty value of the new party should guarantee Harawira more visibility during the official election campaign.
And he will now have the money and resources to avoid being shut out. He can go on the offensive, rather than just battling to hold his seat.
Maori Party, beware. And Labour too.
