"There's a new town centre going in, a recreation centre was just opened by Prime Minister Bill English and the high school was opened," she says.
"There a five high-decile primary schools within the zone and there's not only malls, but important community assets, like a doctor surgery and a pub.
"I've had to look at the history of development in Auckland I can see a similar pattern."
But O'Shea admits that there is a bit of an imbalance with Rototuna. "We have lots of land in Peacockes and Rotokauri, but I sold a house
on the far reaches of the city, on the Te Kowhai side. It was in the city boundary and it was planned to be developed by 2040, she says.
"So I'll be long gone by then but that's the lead time we're talking about."
Chinese and Indian professionals are attracted in high numbers by the perception the community is very safe, O'Shea says.
"One of the characteristics of the area is the perception that it's safe. We never locked the doors when we lived in Rototuna and we left bikes on the lawn. There are still break-ins everywhere but it feels like a safe place."
In the three years to June, 2017 there were 49 break and enter burglaries recorded in Rototuna. In the neighbouring suburbs of Queenwood and Chedworth there were 124 and 212, respectively, according to police data.
As well as professionals, the "lock up and leave" demographic are looking to buy in Rototuna, O'Shea says.
She says there is a proliferation of retirement complexes coming but the future of houses in Rototuna is duplexes.
"People in their 50s or 60s are looking for accommodation that will last. Land is so expensive and the sections are now 140sqm, so they have to build up.
"The suburb is maxed out, there's no land left. There are now townhouses, that in the UK, we would call a semi-detached.
"The concept is alien to New Zealanders because it's only been a generation since New Zealanders were used to having a quarter acre.
"We do duplexes, each on their own title, between 250 sqm and 275 sqm. It works very well for the lock up and leave demographic - who have worked hard their whole life and now have assets and they're proud to be mortgage free."
One of O'Shea's children has bought their first home and the other eight are either actively trying or will be trying to get into their own homes soon.
So although she would describe the suburb as high-density living, she hopes there will be provisions for affordable housing where people want to live.
"It shouldn't be elitist," she says.
"It shouldn't be segregationist or discriminatory on any basis, and that includes an economic basis."
