Countdown will start changing its signage back to the Woolworths name - from next month

The supermarket's announced its transformation programme will include a rebrand, and a refreshed loyalty scheme.

It'll cost 400-million-dollars to renew the stores over the next three years - including upgrading older sites.

Group Managing Director, Spencer Sonn says Tauranga's Bethlehem store will be the first to get the flip in August.

He says by the end of the year there'll be 60, and over the next two years or so all stores will be transitioned.

The official re-brand kicks in early next year.
