Marmite will be back in the pantry by March 20, Sanitarium says.
The company's general manager Pierre van Heerden, told the Campbell Live show it had been a long wait, but he thanked Marmite-lovers for their patience.
Stocks of Marmite ran dry early last year after Sanitarium's Christchurch plant was forced to shut down because of earthquake damage suffered in September 2011.
"It's been a long 15 months,'' Mr van Heerden said.
"We're almost there...the wait isn't that long any more.''
