In response council decided to reduce three parks near the store from a two hour limit to 30 minutes and to hold discussions with Work and Income New Zealand and Bedroom Specialists about providing more car parking.
But Mr Pettigrew said three 30 minute parks would not be enough and he was keen for further talks with council.
Other major changes to parking in Whanganui include an increase in time limit in Victoria Ave from 60 minutes to 90 minutes and a permit allowing tradespeople, sales representatives and delivery vehicles to park for short periods in metered spaces for an annual fee.
Changes are expected to occur early next year.

Meanwhile, a number of speed limit reductions will also come into effect early next year, including an 80km/h limit on the Whanganui River Rd.
Changes include:
•Reducing the speed limit at Ranana township from 100km/h to 50km/h
•Reducing the speed limit on the Whanganui River Rd from 100km/h to 80km/h
