Bachelor: The first rose goes to Mum

Bachelor Arthur Green has always had a special lady in his life - his mum, Cate Hlavac.

She is one of more than 270,000 Kiwis tuning into the TV3 show as a bevy of Kiwi beauties fights for the heart of the 26-year-old.

During the past month he's shared romantic dates with a selection of 21 Bachelorettes, some dates being capped off with tender embraces and passionate kisses. With eight would-be partners left in the show, Hlavac revealed to the Herald on Sunday it was "kind of weird" to see her son kissing the beauties.

"But I try to look at it quite dispassionately," she said, adding whoever won his heart at the end of the show would be a lucky lady.

Asked why he was such a good catch she said it was his "good genes".

"He's adventurous, responsible, trustworthy, happy, unquestionably real and [has a] great sense of humour," says Hlavac, above centre, with Arthur and his sister Emily Green.

Towards the end of the series, Hlavac will get to meet some of the remaining Bachelorettes as Green brings his shortlist of contenders home. She said that would be an "interesting experience".

"It is a crazy mixture of so many elements - meeting potential girlfriends for the first time, getting to know the depth of their true feelings for Arthur, having to ask them 'love' questions," she said.

"I know I can be a bit direct at times, but I don't think in reality I would ask girlfriends on the first meeting about love and babies. I'm sure they will be lovely young women."

For her, the hardest part of watching The Bachelor NZ was seeing her son having to farewell would-be Bachelorettes after each show's rose ceremony.

She had enjoyed watching 23-year-old Pukekohe-based Bachelorette Natalie on the catwalk last week.

"She was stunning, so graceful."

Hlavac joked Green's family was taking the chance to give The Bachelor some good-natured ribbing for his TV persona, saying: "Hell yes ... [it's an] easy sport."
