Staff started stocking the new store four weeks ago with new lines from suppliers.
The St Aubyn store closes tomorrow night to allow the 100 staff to make the move in time for the new store's opening on Thursday, complete with opening specials.
"We've got Levi the big guy coming into town for four days in November," Mr Ricketts said.
"On the first two days he'll do community things like visiting schools and rest homes and then he will be in store."
The business has been going for 51 years, started in Taradale by Mr Ricketts' parents Derek and Audrey. The family now owns Mitre 10 Mega stores in Hastings, Napier and Paraparaumu.
