New Zealander Momoka Kobori and Queensland's Bryden Macpherson share the lead after the first round of the TPS Hunter Valley golf tournament.

Having witnessed Hannah Green's landmark golf victory against men last month, Momoka Kobori, Cassie Porter and amateur Kelsey Bennett are threatening to follow her example.

Young New Zealander Kobori shares the lead with Queenslander Bryden Macpherson after they shot opening five-under 64s in the $200,000 TPS Hunter Valley tournament at Cypress Lakes on Friday.

The Webex Players Series mixed gender tournament was reduced to 54 holes due to the NSW downpours that made play impossible on Thursday.

Rookie pro Porter is in a five-way tie for third at three under, one behind Queensland's Aaron Wilkin.

And Bennett is a further shot back, tied ninth.

Kobori is no stranger to mixing it with the men having won a 36-hole Whitford Park Pro Am on New Zealand's Charles Tour last January and has consistently placed highly throughout the Webex Players Series.

She was tied for ninth at TPS Victoria, tied for fourth behind Green at TPS Murray River and shot 67-66 in the final two rounds at TPS Sydney to finish tied for 11th.

"It was amazing to see Hannah win at Cobram a few weeks ago," Kobori said of Green's breakthrough.

"It's so good to see quite a few of us girls doing quite well in the TPS events the past couple of months. It's definitely good motivation for all of us."
