Helicopters, push-carts and rideable fire engines have all been lovingly crafted as a call-back to the Christmas presents of yesteryear.
A percentage of the proceeds will go back to the Menz shed to help purchase new materials and keep the lights on.
The popular evening events for children also stage a return for 2020.
Two 'PJs in the Cave' nights, on December 4 and 18, will each will have two hour-long sessions, from 6-7pm and 7-8pm.
It's a great opportunity for families to enjoy the Santa's Cave experience in a less busy environment.
Kids can wear their pyjamas, explore the cave, have a hot drink, and finish up with stories read by the man in red himself. The historic carousel will also be operating.
Tickets for PJs in the Cave are $7 for children and $2 for adults. Family passes are also available for $15 (family of 4, with extra children $3 each).
Places are limited so booking is essential, and can be done by calling 0800-4-A-MUSEUM or visiting the museum front desk.
Santa's Cave is open until December 24, 10am to 5pm daily (closing at 12pm on Christmas Eve).
Entry is by donation with funds raised, and additional shop sales, helping keep our city's favourite Christmas tradition alive.
A full timetable of when Santa will be in residence, along with the origins and history of the exhibition, can be found on the Te Manawa website at www.temanawa.co.nz/santa.
