"The kiwis will be the highlight of it but what that will really do is bring to life all the things that happen at night time when we are all in bed. There will be owls in there, there will be lots of interactive experiences for people to touch and feel and experience," the former Melbourne Zoo curator said.
"New Zealand after dark really. It's going to be quite an attractive incentive for people overseas to come and see it but also for the domestic market which is something we would really like to expand upon.
"I think all New Zealanders should have a chance to see the national bird."
As well as the kiwi drawcard, there would be owls, geckos and other nocturnal creatures in the display. Each group of four kiwi is on display for four hours a day so people can see the sleepy native bird moving around.
There will also be a new custom-built classroom and a new exhibition named after local conservationist Arthur Cowan's shed.
"It's a typical garden shed but inside lots of nooks and crannies and drawers that children and adults alike can open and under perspex there will be a weta and other creepy crawlies."
Last year, 41,000 people visited the Kiwi House and this is expected to rise by 5 per cent when the project is completed. Customer spending is also expected to rise by 5 per cent.
At the moment, 60 per cent of visitors come from overseas and Mr Stuart-Higgs hoped the new attractions would increase the domestic market.
The Kiwi House was also expecting a slight rise boost people coming into the country for the Rugby World Cup this month.
"We are expecting a bit of a spike in visitors there, we have already had quite a few inquiries from people in Europe and Great Britain wanting to know what is on offer."
Mr Stuart-Higgs said the ambitious expansion would bring the facility up to scratch with the world class breeding programme run at the centre.
"The original Kiwi House in New Zealand needs to regain the iconic status it had a few years ago."
The Kiwi House has two great spotted kiwi birds and 22 North Island brown kiwis in residence and another five eggs are due to hatch next month.
Mr Stuart-Higgs said people should look out for Atu the great spotted bird who was the star of the show.
"She is just amazing."
